I have exactly the same issue with gaunlet round 4, but its even worse for me now. After i got the same connection error in round 4, i tried to force reset by disconecting my LAN cable.
Now i am completly locked out of UT. I cannot even enter the main manu anymore. I tested my account on a different OC and different network and the same error occurs. My account is stuck in a zombie session because of this gaunlet bug. EA needs to fix this ASAP and reset our stuck sessions!
I'm having the same issue!
This is the worst thing I have ever come across..
