As we will talk about this error and include the best solutions for this issue that prevents some users from playing the action-adventure video game with their friends. 

Causes of Starbound Network Exception Error

Network Exception error basically exists when there is a problem with the router where the game is currently connected. However, there are other factors that can trigger this problem for the Starbound game which we have enumerated below.

Game server maintenance.

A server downtime is one of the common factors why there are instances when players are unable to play or join multiplayer settings on some games. If there are game server outages or an ongoing maintenance, it can affect some features of the application. 

Damaged game files.

Broken or corrupted files stored in the system can also be the culprit why Starbound Network Exception error appears on the screen when trying to join an online match.

Router’s UPnP is not active.

When the router you are using has a Universal Plug and Play (UPnP) feature but it is not activated or turned on yet, then this error will probably exist when playing Starbound. As it will disregard any incoming request from other devices or applications.

Possible firewall restrictions.

The error can be due to the firewall of your computer blocking the Starbound application from running properly. The Windows firewall is designed to protect your device and stop malwares on the web from causing any harm to your device. If it detects suspicious files from the Starbound application or identifies the multiplayer server as a possible threat, it will definitely prevent your Windows PC from connecting to the game server.

Network settings limitation.

A restriction from your network settings can be the reason why the Starbound error was encountered when attempting to play with your friends.

As settings may vary from one router to another, you may contact the Customer Support for your router if you need assistance in activating the said feature.

Port forwarding is also a common process in fixing gaming issues like the Starbound Network Exception code. This action can also improve the overall gameplay and resolves internet connection concerns.
