NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM

Error net::err_cert_weak_signature_algorithm– this looks bad! And, in this scenario, your guess is as good as mine. But let us not judge a book by its cover. Despite how this looks, it is not as difficult to understand. People usually don’t even notice this error much, because it is blindsided by these five words, “Your Connection is Not Private”. Below this title is written in not so bold words, that “attackers might be stealing your information from this site”(depending on which site it is).

How petrifying! The fact that there are no defenders, would sadly make it a one-sided game. Unfortunately, this is not a foosball game. This error “net::err_cert_weak_signature_algorithm” is usually displayed to the users, during one of the most terrible times. So, in this article, we will be briefing you on why this error is displayed on our screens and how to get rid of this error. Not just this, but we will also discuss four other chrome errors, i.e,

  • Net::err_ssl_protocol_error
  • Net::err_cert_common_name_invalid
  • Net::err_cert_authority_invalid
  • Net::err_cert_date_invalid
net::err_cert_weak_signature_algorithm
net::err_cert_weak_signature_algorithm

So, let us dive right in.

Now, What is This “NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM”?

This error is generally displayed to the users when there is an issue with the SSL connection. This error only occurs in Google Chrome when the user is visiting a site and the browser cannot verify the SSL Certificate.

SSL (Secure Socket Layers) or TLS (Transport Layer Security) is nothing but a protocol that is established by keeping the internet connection and the network secure or encrypted. Which keeps us safe and prevents hackers from gaining access to our personal information. So that our private data is secure and not shared with anyone else.

Now that you have obtained a gist of what SSL is, let us talk about why these SSL warnings are being displayed on your screens.

Why does “NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHMoccur?

There could be several situations under why this occurred. Maybe you are just a visitor who was trying to access this website or probably the owner of the website and tried opening the web page, while you were hit with this warning. However, under any circumstances, these SSL warnings occur because:

  • The SSL certificate has expired or maybe isn’t properly configured.
  • Also, the SSL certificate doesn’t belong to that domain.
  • The SSL connection, that is between your device and the server is not completely secure.
  • The SSL certificate is not certified by a well-known or trusted organization, as it very easy for anyone to get an SSL certificate but only a few of them

So, this finally brings us to the bigger question, which is:

How to fix net::err_cert_weak_signature_algorithm

Before you go all “cuckoo”, because the site is not launching. Let us determine, why this error is even occurring in the first place. Let’s begin by trying various methods. Firstly, we are going to figure out whether it is the problem of the site or whether it is the problem of the network. Try opening the same site, on a different device, but make sure the network connection on that device is the same. If the error still persists, then try changing the network connection and then open the website. If the error vanishes, then this could mean only one thing… that there was an issue with your network. So try changing your network connection as soon as possible.

However, if the error stays regardless of how many times we change the device or the network. Then this means that the issue is from the server-side. In this case, you could either file a report or inform the website about this issue or try the below methods.

1. Disable your Antivirus

Don’t worry, we are not going to stab you in the back and this won’t harm your device in any way. The reason why we are asking you to disable your antivirus since it is one of the key reasons for the interference with the website. The antivirus could be considering the site as a potential threat to your device. There could be many reasons, as to why the computer is restricting the site. As everyone has different antivirus software installed. So, it is crucial that you browse through your software and check for any services that are filtering the web services to protect your computer.

3. Go Incognito

Now, there is more than one reason for you to go incognito mode. If you know what I mean! *wink*. Before we try anything else, let us begin with this. Try opening the same site in incognito mode. If the error still carries on then we will need to try different methods. But if you are able to successfully open the site without any warnings or errors, then it means that the problem is with your chrome extensions. They are interfering with the launch of the site for security purposes, and also for the fact that the following site could be harmful to your device.

You can take a chill pill! Because if this is the case, then listed below is the method on how to disable Chrome extensions with ease.

4. Disable Chrome Extension

If you were able to open this website once before and are unable to launch it now, this could mean only one thing. That the issue is with the Chrome extension, and it isn’t rocket science to understand what this is or how to disable it. Let me direct you with steps, to figure out which extension to disable.

Disable Chrome Extension to fix NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM
  1. Go to Google Chrome and click on the three vertical dots at the top right.
  2. As soon as another panel drops down, hover the cursor over More Tools
  3. Over here, you will find an option called Extensions, click on it.
  4. Make sure to turn all the extensions off and check again if the error still persists.
  5. If the error is no longer there. Then turn on each extension one-by-one to see which one was the problematic one.

Usually in this case the problem tends to be the antivirus. As you see it in extension site enabled. Sometimes it’s not an antivirus but it is some sort of a security-related extension. So be careful and search thoroughly if you have too many extensions on your device.

5. Try Resetting your Network Settings

If you have read my previous paragraph, then by now you should have figured out whether the problem is with the site or your network. However, if the network is the problem at hand in this case, then we might have just the right solution for you.

Which is “resetting” it. As it is possible that despite having a good network, the site is working perfectly on the other devices. Thus, you must try resetting network settings on your device, by following the mentioned methods. Point to remember: you require an Administrative Account in order to make the following changes. I will be mentioning both, in the case of a Windows or a MasOS user.

For Windows:

  1. Go to the settings or simply type “Network & Internet” in the search bar
Try Resetting your Network Settings
  1. Once open, scroll to the bottom of the page.
  2. You will find an option “Reset Network”, click on it.
reset network
  1. After picking this option, you will be redirected to a page.
  2. On this page, there will be another option “Reset now”, select it.

6. Clear the SSL Cache

Most of the time, the webpage has re-issued the latest SSL algorithm. Unfortunately, the browser contains our earlier cache memory, therefore, showing the error. So, allow me to guide you through this journey of “clearing cache”. I am sure you won’t be disappointed.

  1. Let us begin opening Google Chrome (duh)
  2. Then click on the three vertical dots shown at the top-right of the browser, otherwise known as Menu or Customize & Control Panel
  3. Then after the dropdown, click on settings.
  4. When you reach “chrome://settings/”, scroll down and select the Privacy and Security option.
Privacy and Security
  1. Or you could simply type up this URL: chrome://settings/privacy.
  2. When you reach this page, click on Clear Browsing Data.
Clear Browsing Data
  1. Soon after, another site will arise, make sure you are in the Basic region. Then click on Time Range and select All time.
Clear net::err_cert_weak_signature_algorithm
  1. Finally, click on Clear Data.

Make sure that, when you are clearing the data/cache the time range is set to all time and not just 1 hour or 24 hours or 7 days or 4 weeks. As soon as the job is finished close the browser and restart your device.

Make sure that, when you are clearing the data/cache the time range is set to all time and not just 1 hour or 24 hours or 7 days or 4 weeks. As soon as the job is finished close the browser and restart your device.

7. Clear the DNS Cache

Guess what? We have another “cache” up our sleeve, in case the previous one didn’t work. By now, it must be getting really painful, as the error has still not disappeared and you have made no progress yet. But don’t worry as every cloud has a silver lining. This is even simpler than the previous one.

All you gotta do is…

  1. Open Google Chrome
  2. Type in: “chrome://net-internals/#dns
  3. Click at Clear Host Cache.
Clear the DNS Cache

And BINGO. This will work like a charm if DNS is the issue in your case. See more about the DNS server isn’t responding: Fixing DNS issue.

8. Clear SSL State

Yeah, don’t worry. This is not a cache. I’m not sure if you know this yet, but setting up an SSL certificate takes time and cannot be done instantly. This is because it requests the server for a copy of the digital certificate from their site and only after it is verified and installed, it proceeds for data transfer. Now, as this process takes quite a long time, to avoid the repetition of this procedure, what the computer does is, it saves the SSL state in its directories. Thus, it can retrieve it locally, rather than going through the server and fetching it from there again and again.

Due to this, the problem could sometimes be with the SSL state, already installed in our device. So all we are going to do is clear the SSL sheet and these are the following steps to do so:

  1. Press Windows + S and search for Control Panel.
  2. Once we reach Control Panel, click on Network and Internet
Network and Internet
  1. Then, select Internet Options.
net::err_cert_weak_signature_algorithm
  1. Right after which a pop-up will appear, select the Content option at the top.
Content
  1. And finally, under the certificates section, choose the Clear SSL State button.
  2. Click at Apply and right after that OK.
  3. Restart your device.
  4. net::err_cert_weak_signature_algorithm get fixed

9. Reset Chrome

If you have any bookmarks or some cool theme, make sure you remember to note them down. As once you reset Chrome, it will be set to its original / default settings. This method could also be quite handy. Also, know about: Chrome Flags: chrome://flags.

  1. Go to chrome setting, i.e, chrome://settings/
  2. Click on the Advanced option.

  1. Scroll all the way to the bottom of the page, and you will see “Reset settings to their original defaults”, click on it.
Reset settings to their original defaults
  1. A final confirmation pop-up will appear on the screen, then select “Reset Settings” Now, you will not see net::err_cert_weak_signature_algorithm error.

10. Pushed to the Wall

When push comes to shove, we need to opt for this alternative. Which states that there is another way of accessing the site without following any of the above methods. However, it comes along with its own sets of risk factors. When the error occurs you can click on the Advanced option, ignore the safety precautions and proceed to the site.

Advance net::err_cert_weak_signature_algorithm

But, as I said, this will have its own sets of risks. By doing so, not only are we ignoring the security and trespassing, but we are also endangering our own device to possible threats. As this move contains a lot of danger, try to steer clear of this way. But if you are 100% sure about the authenticity of the site then definitely go for it.

Otherwise, you will end up getting Bamboozled!
