Connection hotfix

Looks like i had to touch so much files that i completely forgot to test the new reconnect functionality which opened up some major mistakes i made during the refactoring.

Anyway, i tested it and fixed all the code. so hopefully it's less broken :)

Sorry for making so much noise.
