How to Fix “Marvel Rivals Server Connection Failed”
If Marvel Rivals failed to connect to server, try the fixes below to troubleshoot server status, network connection, launcher, and game file issues.
Fix 1. Check Marvel Rivals Server Status First
Before troubleshooting your PC or network, check whether Marvel Rivals servers are down for everyone. If there is scheduled maintenance or a widespread outage, the Marvel Rivals Server Connection Failed error may disappear once the servers return online. Here are the best ways to check the current server status:
- Official Marvel Rivals X Account: Check Marvel Rivals on X for maintenance announcements, outage notices, and updates from the developers.
- Official Marvel Rivals Discord: Join the Marvel Rivals Discord server to see official updates and real-time reports from other players.
- Downdetector: Check Downdetector for spikes in user reports. A sudden increase may indicate a widespread Marvel Rivals server issue.
- Community Reports: Check Discord discussions or social media to see whether other players are experiencing the same Marvel Rivals connection failed error.
If many players are reporting issues at the same time, the issue is likely server-side. If the servers appear online and Marvel Rivals can't connect to server only on your device, continue with the fixes below.
Fix 2. Restart Marvel Rivals and Your Game Launcher
Temporary launcher or login-session errors can cause Marvel Rivals connection issues and prevent the game from reaching its servers.
Step 1. Completely close Marvel Rivals.
Step 2. Exit Steam or Epic Games Launcher from the system tray.
Step 3. Reopen the launcher and start Marvel Rivals again.
If Marvel Rivals still can't connect to server, restart your PC and try again. Restarting the game client can also clear temporary connection or launcher-related errors.
Fix 3. Restart Your Router and Stabilize Your Connection
An unstable connection, packet loss, or temporary routing problem can cause Marvel Rivals connection failed errors even when websites and other apps still work normally.
Step 1. Turn off your router or modem for about 30 seconds.
Step 2. Turn it back on and wait for the internet connection to fully restore.
Step 3. Launch Marvel Rivals and test the connection again.
For better stability, use Ethernet when possible and pause bandwidth-heavy tasks. Restarting your router may also fix temporary Marvel Rivals connection issues.
Fix 4. Verify Marvel Rivals Game Files
Missing or corrupted game files can cause Marvel Rivals connection issues, especially after an update.
👉 On Steam
Step 1. Open Steam > Library.
Step 2. Right-click Marvel Rivals > Properties.
Step 3. Go to Installed Files > Verify integrity of game files.
👉 On Epic Games Launcher
Step 1. Open your Library.
Step 2. Click the three dots next to Marvel Rivals.
Step 3. Select Manage > Verify.
After verification finishes, install any pending updates and restart the game.
Fix 5. Change DNS and Flush the DNS Cache
DNS issues can sometimes cause Marvel Rivals connection failed errors by disrupting access to the game’s online services.
Step 1. Search for Command Prompt and select Run as administrator.
Step 2. Enter: ipconfig /flushdns
Step 3. Restart your PC and launch Marvel Rivals again. If the issue continues, try switching to a public DNS:
- Google DNS: 8.8.8.8 / 8.8.4.4
- Cloudflare DNS: 1.1.1.1 / 1.0.0.1
If Marvel Rivals can’t connect to server with your current DNS, changing it may help restore the connection.
Fix 6. Allow Marvel Rivals Through Windows Firewall
Firewall or security software may block Marvel Rivals or its launcher from reaching the game servers.
Step 1. Open Windows Security > Firewall & network protection > Allow an app through firewall.
Step 2. Click Change settings > Allow another app, then add the Marvel Rivals executable from its installation folder.
Step 3. Allow Marvel Rivals and your launcher on the active network, click OK, and relaunch the game.
Tip: Avoid disabling your firewall completely; adding Marvel Rivals and its launcher as exceptions is safer.
