Hey my Problem is simply said that i had a DC 2 days ago for about 10 minutes, and im unable to rejoin my own hosted server.
No matter how much i try it doesnt work , i really need a fix for this , i mean gamebreaking isnt even close to what this bug is.
I reinstalled everything (Steam,Conan,Modem reset,server backup loaded), checked server settings and Ports , Internet etc. i really dont have a clue on how to fix this . Please help me …

Steps on how to reproduce issue:
1.Get a DC
2.try to join after it
3.stay in infinite loading screen till you die
4.Feel the Pain
