Satisfactory has officially launched its 1.0 release after nearly five years in development. This significant update brings a wealth of new content for players to explore. However, it has also presented some technical challenges, particularly for those operating dedicated servers. If you’re encountering the “Failed to Connect to the Server API”error in Satisfactory, here are the steps to resolve it.
How to Fix the “Failed to Connect to the Server API”Error in Satisfactory
When running a dedicated server in Satisfactory, several adjustments are necessary due to the 1.0 update, particularly regarding port forwarding.
Forward All Ports to Both TCP and UDP
The server API now operates on TCP rather than UDP. Thus, you must forward ports 7777 (Game Port), 15000 (Beacon Port), and 15777 (Query Port) to both UDP and TCP on your router. Forwarding all three ports to both protocols is essential for the proper functionality of dedicated servers.
Remove the -multihome Command
If you utilized the -multihome=0.0.0.0 command for your dedicated server, it is no longer necessary since the server defaults to ipv6 and ipv4.
Unraid Users: Switch Network Type from Bridge to Host
For Unraid users, change the Network type setting from Bridge to Host.
Remember, the critical adjustment is to forward the necessary ports to both TCP and UDP as mentioned earlier, particularly the essential 7777 game port. Once configured, your dedicated servers should correctly appear in the Server Manager accessible from the Main Menu in-game.
The initial release of version 1.0 has been predominantly smooth; however, some users have experienced Unreal Engine crashes in Satisfactory, which can be remedied with a simple adjustment in the launch options.
