[1.14.4] Is it possible to use the "runClient" configuration on the "runServer" configuration?

[Keheck]

I am currently trying to make my mod server compatible, and Forge conveniently sets up with a "runServer" and "runClient" configuration.

However, it seems like I'm not able to join the server created by "runServer" with the client from "runClient". I'm assuming it's because the "runClient" client is not a valid Minecraft account, since using my normal one works just fine.

 

It would be nice if it was possible to let the "runClient" client join the server, since I only have one valid Minecraft account atm. Does that work somehow?

 

Edit: The type of error I get is Failed to log in: Invalid session (Try restarting your game and the launcher). Neither restarting the game nor the IDE (just to be sure) helped.

When looking at the Console output of the server I get the following message: [Server thread/INFO] [minecraft/ServerLoginNetHandler]: com.mojang.authlib.GameProfile@4c3f1902[id=<null>,name=Dev,properties={},legacy=false] (/127.0.0.1:52506) lost connection: Disconnected, while joining via my legal Account gives me [User Authenticator #1/INFO] [minecraft/ServerLoginNetHandler]: UUID of player Keheck is 65831990-3d68-4646-95c9-2b75429faf43

Weird, those options have always worked for me.
