How to repair the “Connection failed” error in Stardew Valley

Restart the game or system

It is always recommended that you perform a soft restart of the game and client if you are having problems starting the game or connecting to the server.

You can also reboot your Windows computer/laptop to fix temporary errors in the software, etc. If the game is already running in the Steam client, close/exit the game. Close the Steam client completely.

To reboot your system, click Start -> Press Power -> Select Reboot. Wait for your computer to reboot automatically. Now try running the client and the game to check the problem.

Turn off antivirus software or firewall

It looks like the installed antivirus or firewall software is conflicting somewhere, and one of them is preventing your game or client from working properly.

More often than not, antivirus software or firewalls will prevent game servers from connecting to the network, even if you have an active Internet connection. In this case, you can either disable the application or create a bypass rule and your game will no longer be affected by the antivirus program or firewall.

However, keep in mind that disabling the antivirus or firewall exposes your computer to the risk of easily getting additional threats or security holes.

  1. Open Task Manager (Ctrl+Shift+Esc) -> Go to Processes and select the Steam game or service, then click End Task to forcibly close it.
  2. Now open an antivirus program (Defender or a third-party program) and turn off real-time protection, web filtering, quick/full scanning, etc.
  3. Also, click Start -> Firewall Type and select Firewall and Network Protection.
  4. Click Domain Network -> Disable Windows Defender Firewall.
  5. Then go back and click Private network -> Disable Firewall.
  6. The same procedure applies to the public network.

If you don’t want to disable the antivirus or firewall on your computer, try adding an exception to the antivirus or firewall to allow the game/pairing without problems.

Join the game through the Steam launcher

Sometimes players are unable to join the game directly through the game interface due to an error. If this is your problem and you don’t know what to do, follow these steps.

  1. If the game is already running, quit the game first.
  2. In the Steam client, go to the friends list.
  3. Now find one of your friends who is playing Stardew Valley and click on it.
  4. Click Join Game -> Try to start the game to check the problem.

Disabling the VPN client

VPN stands for “virtual private network.” This service essentially gives you an anonymous identity that allows you to access the Internet without revealing your real IP address or even your network connection. A VPN creates a mask or layer on top of your actual Internet Protocol (IP) that is virtually untraceable, and users can access any sites or content that cannot be accessed because of server or regional restrictions.

Regardless of which VPN service you’re using on your computer, if you’re having trouble connecting to the Stardew Valley server, try temporarily disabling the service. Then reboot your computer and try running the game again.
