4.15 Dedicated Server can`t load map

So i had a big Project wich is from Laucher Version around 4.8 and i wanted to make a dedicated server now for it since it is a MOBA. I was following the guide here: A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums .
And everything was going quite well. I got my server files and seemed to get the server running but when i started my game to connect to it with the open lv node and the local ip in there it somehow gives me an error and kicks me out of the server again because it says:Servers cant open network urls and i dont really know what to do since i only followed the guide. Ill include a screenshot of the Log.

Hey -

I was able to follow the directions on the page you linked to build/launch a dedicated server locally. Launching and connecting to the server were done on the same computer. The error you mention seems to indicate the server is attempting to open/ a network location. Is the project referring to a network path anywhere?

Well the path behind the ip reffers to where the map is saved inside the content folder. Novice is the map i am trying to load. But i couldnt find the map file inside the build folder (Windows x64), but i guess that is because of the .pak files that unreal generates.
Also it should be content not game at the start. Don`t know why game is there.
the path of the file is: LOCOR\Content\Map\Novice\Novice.umap

Are you able to reproduce this in a new project? I tried with a new project and still did not have the network connection error mentioned. If possible, could you provide a copy of your project for me to test the connection issue directly?

In a new Project i dont get this Error. Really strange. Maybe i ■■■■■■ something up in the time since the project is really old. I will redo the project in a new fresh one. Will be some work but will be better that way. Case solved for me. Sorry i didnt try that out first.
You can mark the question as solved. And thank you verry much for the fast answers.
