How to Fix Rocket League Error 91?

Part 1: What is Rocket League Error 91?

Rocket League e rror 91 is a connection-based matchmaking error that typically occurs when attempting to enter a private match, join a friend's lobby, or host a custom game. Even though the message mentions "server is from the wrong region, Rocket League," the root causes are not always region-related.

⚠ Common Causes of Rocket League Error 91

• Server mismatch caused by Epic/Rocket League backend issues

Part 2: How to Fix Rocket League Error 91?

Fixing this error is not a complicated thing, especially when you are following our guide. Below are the 4 most effective solutions that you can try:

Fix 1: Change the Region in the Settings of the Private Match

Many players encounter Rocket League error 91 simply because the private match is set to a region that doesn’t match everyone’s location. This often happens when someone accidentally leaves the region set to EU, Asia, or Oceania while teammates are in North America.

Before trying anything more advanced, always start with this quick fix. Here is how to change regions in Rocket League:

• Go to the “Main Menu” in Rocket League and click the “Gear Icon” to open the settings.

• Now go to the “Gameplay" tab and open the "Region" option. Here, you need to choose the right region and click "Close" to fix the issue.

  

Fix 2: Correct Windows Timezone

Sometimes, PC’s incorrect system time or timezone can also interfere with Rocket League’s server authentication. Modern online games rely on synchronized timestamps to validate region and session information, so even a small mismatch can cause error 91.

Fixing your timezone realigns your PC with Epic’s servers and often resolves the issue instantly. It’s one of the easiest fixes and should be done before other troubleshooting.

• Press "Win + I" on your computer to open settings and go to "Time and Language."

• Click the "Date and Time" option, then toggle off the option "Set time zone automatically," then toggle on this option again.

  

• Now toggle off the “Set time automatically” option and toggle it on again to ensure your time and date, along with timezone, are set according to your location.

Fix 3: Ask Party Member to Host

Rocket League error 91 can show up when one player in the party has stricter NAT rules, unstable Wi-Fi, or inconsistent regional routing. If the current party leader is matched to an incompatible server, everyone else receives the error. Simply switching hosts allows Rocket League to reassign the server region to someone with a cleaner connection.

This often bypasses the server's mismatch entirely. It’s a fast, practical workaround that works for many players. You can also become the host to fix the issue, and here is how:

• Select the "Play" option from the Main Menu and select "Private Match."

  

• Select “Create Private Match” and customize the settings as per your Party preferences.

• Click "Create Match," and you can invite your friends, or they may join you in fixing the server issues for everyone.

Fix 4: Switch to Wired Ethernet

Wi-Fi can introduce randomness in routing, packet loss, or regional server selection, any of which may trigger Rocket League error 91. Wired Ethernet creates a stable, low-latency connection that ensures accurate matchmaking and region assignment. Switching to Ethernet eliminates these inconsistencies completely.

• Open "Win + I" to open settings and go to "Network & Internet," then turn off "Wi-Fi.

• Connect the Ethernet cable to your computer and wait for the computer to connect to the internet.

  

• Restart the Rocket League game and try again.
