Unable to connect to official servers or Steam hosted games

Hello, IMEI!

Sorry to hear you're experiencing this issue. As it's not just a single server or multiplayer method, I would assume it is something on your end rather than the game itself. I would suggest doing all of the below (I appreciate you have already validated)

• Verify your game files in Steam

• Right click on Space Engineers in Steam Library → Properties → Local Files → Verify Integrity of Game Files

• Delete SpaceEngineers.cfg file

• It means your game configuration will be deleted
• You can access your SpaceEngineers.cfg by typing %appdata% into your Windows search bar and you will be redirected to the hidden Roaming folder. After that just follow: \Roaming\SpaceEngineers.

• Delete ShaderCache folder

• Same access as SpaceEngineers.cfg

• Back up your whole Space Engineers Roaming folder and delete it
• Restart Steam
• Reinstall the game
• Make sure your operating system is fully updated

I would also check your firewall settings and also any antivirus software. If at all possible, I would also suggest trying to connect on another PC inside your house. You may also be able to try connecting tethered to your phone network to see if you can connect this way to at least narrow the issue down a little.

I'm doing that right now and I'll let you know what I find.

I had to do a full uninstall/reinstall and remove all references to the EXE in Windows Firewall before it started working again.

Hello, IMEI!

Thank you for getting back to us. I'm glad it has now started working again after you have done these things.

I will close this thread for you
