For me, I had many connectin problems in Vanilla as well as in PR. For me the Dualcore Optimizer fixed that thing. Then I had connection problems again in Vanilla and PR and I deleted my profile, created a new one... fine.
I understand that you are upset, but you only see your problem (which is ok), but the DEVs have hundreds of problems, complaints, bugs to look over. I think you can understand that as well.
And so, like in every business, you have to priorise things. And a connection problem of "some" users are not that priority as other things.
20,000 reviews you say, ok, BUT from that 20,000 reviews are many guys like me without problems who are only willing to help or to read the new posts. One guy is telling about a problem, 5 guys trying to help.... so its 6 reviews, but only one guy with a prob.
*Got the point*?
Ok, that wont help solve your problem, but there is a saying here in germany: "The sound makes the music" and i guess with your CAPS and angry writing there are not that much guys willing to help you anymore...
Btw. I don't mean it offensive in any way, I am willing to help and this is just my point of view.
I also don't know anyone from the DEV team, but I am in IT business too, so I know about the work.
Good luck anyway to you and I hope you will get your issue fixed!
I have similar one's, but no pop up comes up for me to allow them, ive also tryed turning everything off on my computer eg. Firewall, Antivirsus, spyware etc... and still disconnects me, this is very weird hope it gets sorted soon.
Look at my post above, I mentioned quite a few "fixes" that some people had success with. Those are all the supposed tricks I learnt from dealing with the problem for over a month now. I can say that the above things I did certainly make the problems less frequent but I still get them.
