Try using the latest beta build and tell me if it still happens. [Beta] Honorbuddy Beta Builds I am not sure if this will be a definite fix, but it's worth a try.
i got also dc ( after 10 -30 min max)each time i use lates beta or the 2.5.6441.507, ofc fresh install
I noticed a DC as well with the beta, but it is a lot longer then .507 Blizzard needs to better tune their new telehack checks. It also affects their legit users.
I was running on my old pc i have ekstra... and i did try to run the bot it that pc and it was going for 6 hours strong no dc... but on my main pc it keeps doing it >.<
