Okay, In the past i posted about the ■■■■ multiplayer tutorial with steam that’s 2.5 hours long and was asking why the hell isn’t my project working… No help from that SO I remade the entire project and now at no surprise ITS NOT WORKING STILL! it’s made on the same project version but now when ever i attempt to join the server from the server list it crashes with these errors:
I am not entirely sure, but as far as I can tell, the widget should not be the issue for the crash. However, concerning the widget: Is it possible, that you have not set the reference? You have this “MainMenu”-Variable which should contain your MainMenu widget (or the reference to it). If it has not been set after you created your MainMenu-Widget-Instance, it is emtpy though and might cause such an error…
Furthermore, the other error looks like the engine is unable to find the map. Have you double checked that everything is spelled correctly and the map is exactly where it should be? (Maybe just for testing purposes, create an emtpy map, put it in the root folder of your project and try to use this one…)
But you were able to open the map with the host/server?
Last but not least: If you use OnlineSubSystemSteam, testing with PIE could cause errors. Better use Standalone Game or package the game and test it on two computers with two different steam accounts…
