Rocket League Error 91 is one of the most frustrating connection problems players face, often appearing right when they are ready to jump into a match. In 2026, despite improved servers and network stability, this error still affects players across PC, PlayStation, Xbox, and Nintendo Switch. Understanding what it means and how to fix it quickly can save time, prevent ranked penalties, and get players back onto the field faster.
TL;DR: Rocket League Error 91 is a server connectivity issue that prevents players from joining online matches. It is usually caused by server outages, unstable internet connections, firewall interference, or outdated game files. Quick fixes include restarting the game and router, checking server status, adjusting firewall settings, and updating the game. Most players can resolve it in under 15 minutes using the steps below.
What Is Rocket League Error 91?
Rocket League Error 91 typically appears when the game fails to connect to Epic Games or Rocket League servers. The error message may read something like “Error while communicating with Rocket League servers” or simply display “Error 91” during matchmaking.
This issue primarily affects online features, including:
- Joining ranked or casual matches
- Accessing tournaments
- Creating or joining parties
- Viewing friends lists
In most cases, the problem is network-related. However, corrupted files, outdated versions, or security settings can also trigger it.
Why Error 91 Happens in 2026
Even with upgraded infrastructure, online games remain dependent on real-time connectivity. Several factors commonly cause Error 91:
- Server maintenance or outages
- Unstable internet connection
- Strict NAT type
- Firewall or antivirus blocking the connection
- Outdated Rocket League version
- Corrupted cache or game files
Identifying which of these is responsible makes troubleshooting much easier.
6 Fixes That Work in 2026
1. Check Rocket League Server Status
Before changing any settings, players should confirm whether the issue is on their end. Server maintenance or outages are common after updates or new season launches.
How to check:
- Visit official Epic Games server status pages.
- Check Rocket League’s social media for announcements.
- Use third-party outage trackers.
If servers are down, the only solution is to wait. Attempting other fixes will not resolve a global outage.
2. Restart the Game and Device
This may sound basic, but many instances of Error 91 are caused by temporary connection glitches.
Steps:
- Fully close Rocket League (do not suspend).
- Restart the console or PC.
- Launch the game again.
This refreshes network allocation and clears minor system conflicts.
3. Power Cycle the Router
A router refresh resolves IP conflicts and clears temporary cache issues.
How to power cycle properly:
- Turn off the router.
- Unplug it from power.
- Wait 2–3 minutes.
- Plug it back in and wait for full reconnection.
Players using Wi-Fi should also consider switching to a wired Ethernet connection for improved stability.
4. Adjust NAT Type and Port Forwarding
A strict or moderate NAT type can prevent proper matchmaking connections.
Recommended NAT Type: Open
To improve NAT:
- Enable UPnP (Universal Plug and Play) in router settings.
- Forward Rocket League ports specific to your platform.
- Restart the router after applying changes.
Port forwarding varies by platform, so checking official 2026 port lists for PlayStation, Xbox, Switch, or PC is recommended.
5. Update Rocket League and Your System
Outdated game clients may fail to connect to updated servers.
Check for updates:
- Epic Games Launcher (PC)
- Console game update section
- System firmware settings
Installing pending updates resolves compatibility mismatches that can trigger Error 91.
6. Verify Game Files or Reinstall
Corrupted files can disrupt server communication.
On PC:
- Open Epic Games Launcher.
- Select Rocket League.
- Choose “Verify” from settings.
On consoles:
- Delete the game.
- Reinstall it from your library.
While reinstalling takes longer, it often completely resolves persistent connectivity issues.
Comparison Chart: Quick Fix Overview
| Fix | Time Required | Difficulty | Best For |
|---|---|---|---|
| Check Server Status | 2 Minutes | Very Easy | Suspected outages |
| Restart Game/Device | 5 Minutes | Easy | Minor glitches |
| Power Cycle Router | 5–10 Minutes | Easy | Connection instability |
| Adjust NAT/Port Forwarding | 15–30 Minutes | Moderate | Strict NAT issues |
| Update Game/System | 5–20 Minutes | Easy | Version mismatch |
| Verify/Reinstall Game | 20–60 Minutes | Moderate | Corrupted files |
Advanced Tips for Persistent Error 91
If none of the six fixes work, players can try additional measures:
- Disable VPN services – VPNs often interfere with matchmaking.
- Temporarily disable antivirus/firewall – Ensure Rocket League has network permissions.
- Flush DNS (PC only) – Use Command Prompt and enter: ipconfig /flushdns.
- Contact ISP – Some internet providers restrict gaming ports.
Consistent connection drops may indicate deeper network hardware issues requiring router replacement.
How to Prevent Error 91 in the Future
Prevention is better than troubleshooting mid-session. Players can reduce the likelihood of seeing Error 91 by:
- Keeping automatic updates enabled
- Using wired internet where possible
- Restarting routers weekly
- Avoiding public Wi-Fi networks
- Monitoring server announcements before season launches
Competitive players especially benefit from stable infrastructure, as disconnects can impact rank and tournament eligibility.
