Server Error: TravelFailure: ClientTravelFailure, Reason for Failure: 'Servers can't open network URLs'

Doing a clean build worked.However when clicking the project.exe I dont get the Join succeeded message


I get all the way to here: Screenshot - 6a9624348f3a982ace9322c44173a758 - Gyazo
which is good
No error this time but its just a black screen. They did have me delete the player start capsule and set the default map to the testLevel.

The thing is, when i click I hear the actions of my game, but see nothing. Just a black screen and no server log for a successful login.
Hmm
