How to fix error 91 in Rocket League

Rocket League ^[1] has been around for years now, with the game initially growing in popularity thanks to it being given away as a free PS Plus game. However, as it is with every online competitive game, Rocket League has many technical issues that may stop players from properly enjoying it.

Error 91 in Rocket League, for example, is an extremely common issue that arises when the player has connection issues. Potential fixes that may fix this include using a wired connection instead of a wireless one, having the friend host, changing the region, or some technical fixes like setting up port forwarding or switching to a public DNS.

Without any more delay, here’s how you can fix error 91 in Rocket League. 

Use a wired connection for better stability

Sometimes, error 91 is not always about the servers but your internet connection. A shaky connection makes it hard for your game to reach the servers, especially when setting up a private match or online free play. Rocket League might struggle to communicate properly if your Wi-Fi keeps disconnecting, has weak signal strength, or is overloaded with too many devices.

The easiest way to fix this is to switch to a wired Ethernet connection by plugging your device directly into the router. It helps reduce lag and makes a big difference in dropped connections.

Let a friend host the match to bypass the error

Error 91 does not always affect everyone in the party, which is why one of the most reliable workarounds is to let someone else in your group host the match. It sounds simple, but it can immediately get things working again. To do this, have your friend invite you to their party and let them create the private match or free play lobby.

This happens because of how Rocket League’s matchmaking servers are set up, causing the host’s connection to glitch or fail to sync properly with the server. Switching hosts resets the session using a different connection, clears up the issue, and gets everything working again.

Change the region from recommended to your actual server

If you play on Rocket League’s automatically assigned region, you may get error 91. It is supposed to connect you based on ping and location, but it often assigns you an overloaded one with issues.

To fix this, you can manually set your server region instead. Head to the main menu, click the gear icon in the top right to open Settings, go to the Gameplay tab, and look for the Region option. Switch it to the region you usually play in. It tells the game to stick to one server, avoiding mismatches that could be causing the issue.

Set up port forwarding to help Rocket League connect to servers

Your router might block Rocket League from reaching the servers and cause error 91 if a wired connection does not sort things out. Port forwarding can help, as it tells the router to let Rocket League traffic pass through specific channels.

Setting this up sounds technical, but it's doable. First, access your router’s settings by typing your default gateway IP into your web browser (you can find it by opening Command Prompt and typing ipconfig). From there, log in with your router’s credentials, and once inside, look for the port forwarding section and add these ports: 80, 443, 3478, 3479, 5060, 5062, 5222, 6250, and 12000-65000 (all TCP/UDP).

Switch to a public DNS for a more reliable connection

If you still get error 91, try switching to a public DNS. By default, your internet uses your ISP’s DNS servers, which are unstable.

Swapping to something like Google DNS (8.8.8.8 / 8.8.4.4) or Cloudflare DNS (1.1.1.1) can give your connection a cleaner route to the game’s servers. To do this, head to your network settings and manually assign those DNS addresses. Be careful and only change the above settings, leaving everything else untouched.

Sync your Windows clock to your timezone

Having the wrong time on your PC or console can interfere with Rocket League’s ability to connect to the servers. Online games use time-based checks for security, so if your device’s clock is slightly off, it can cause server issues, like error 91.

Fixing it is super simple. On Windows, right-click the clock on your taskbar, head to Adjust date/time, and choose both time and time zone to set automatically. Then, hit Sync now to align your system with the internet time. This minor adjustment helps avoid annoying server problems.

Add a firewall exception for Rocket League

If nothing else works, your firewall could be preventing the game from connecting to the servers properly. While it is meant to keep your system safe from harmful traffic, it can unintentionally get in the way of your game and prevent key resources from making it to the game’s servers and vice versa.

To fix this, you must manually tell Windows Defender Firewall that Rocket League is safe. Search for Windows Defender Firewall in your start menu, then click Allow an app or feature through Windows Defender Firewall. Look for Rocket League in the list and make sure all the boxes are checked. It should let you get back to queuing matches without hiccups.

FAQs

Why is my Rocket League lagging even though my internet seems fine?

Lag in Rocket League can happen even with fast internet if your connection isn’t stable. High ping, packet loss, or jitter can cause gameplay delays. This might be due to Wi-Fi interference, background downloads, or too many devices on the same network. A wired Ethernet connection is often more reliable for online games.

What’s the best internet speed for playing Rocket League smoothly?

Rocket League doesn’t need extremely fast speeds. A stable 5–10 Mbps download and 1 Mbps upload is usually enough. However, the key is low latency (ping), not just speed. A ping under 50ms gives smoother gameplay, so focus on reducing latency rather than boosting download speed alone.
