Error “Failed to sync project MyProject with content service” prevents session launch

Hey,

Whenever I open my UEFN project, I’m greeted with an error message:

I first had this issue about 8 months ago. I am still having the same issue despite hours upon hours of troubleshooting.

This connection issue prevents me from launching a session or publishing my project. I have tried logging in and/or out of the launcher, verifying the game files, and restarting my computer, none of which have solved the issue.

There have been two times when I have been able to open this project without the error, launch a session, and play my project in a game instance, but I could not for the life of me figure out how to replicate these successes.

Here’s the error as it appears in the output log:

LogValkyrie: Error: Failed to sync project MyProject with content service:
Failure ErrorCode=errors.com.epicgames.online.generic.connection_failure, Message=Connection to the server failed., Raw=connection_failure

Any assistance would be greatly appreciated!

That’s a different error from the one this discussion is about. Maybe you can find a solution if you make a new post about it?
