7.  Scroll through the apps and search for Factorio.
8. Make sure the Private and Public boxes are checked.

Play via Steam

If you or your friend are having trouble joining the Factorio server, ask them to do it through Steam. Several users have reported that when they play through Steam they don’t get the error or server issues.

2. Check if you have configured port forwarding

  1. Go to your local connection settings and note the local IPv4 address. It should look something like this:
    192.168.1.1
  2. Then open your internet browser and enter your local IPv4 DNS address.
  3. Enter your username and password. The username is admin and the password is admin/password by default for most routers. You can also refer to your router’s manual to see your login details.
  4. Open Port Forwarding on your router’s configuration page.
  5. Enter 34197 in the Service Port field.
