Unknown error while communicating with rocket league

Why Do You Encounter Unknown Errors in Rocket League?

  • Inadequate Network Connection: The foremost cause of communication errors in Rocket League could be an unstable network connection. The game requires a strong and stable connection for seamless gameplay, and any inconsistency can cause errors.
  • Server Issues: Occasionally, the problem might not be on your end. Rocket League servers may experience issues, leading to communication errors. Scheduled maintenance or unexpected server outages are common culprits.
  • Corrupted Game Files: Corrupted or missing game files can also trigger the error. If the game’s files are tampered with or incomplete, it can disrupt the communication process.

How to Fix the error

Fix 1: Checking and Stabilising Your Network Connection

Often, an “unknown error while communicating with Rocket League” can occur due to an unstable or weak network connection. Here are detailed steps to check and stabilize your network:

  • Step 1: Test Your Internet Connection: Firstly, verify your internet connection’s stability. You can do this by visiting any online speed test website. Check your download and upload speeds, and the ping.
  • Step 2: Check for Network Interruptions: Next, ensure there are no interruptions to your network connection. You can do this by temporarily disconnecting other devices using the same network. This will help determine if other devices are consuming significant bandwidth, causing instability.
  • Step 3: Switch to a Wired Connection: If you are using a Wi-Fi connection, consider switching to a wired Ethernet connection. Wired connections typically provide more stability and lower latency than wireless ones.
  • Step 4: Restart Your Router/Modem: If your connection is still unstable, try restarting your router or modem. Unplug the device from the power source, wait for about a minute, then plug it back in.
  • Step 5: Contact Your Internet Service Provider: If all else fails, it may be time to contact your Internet Service Provider. They can check if there’s an issue from their end affecting your connection.

By ensuring a stable and robust network connection, you can reduce the chances of encountering the error.

Fix 2: Verifying the Integrity of Your Game Files
