Hello everyone,
Update on this issue - today we implemented a few smaller changes to the server software that should speed up connection a bit. As for the main issue with connection going offline/online - our specialists are still working on this and hopefully today or tomorrow we'll implement a patch that eliminates this problem.
P.S. Most likely updating Remote Utilities won't be necessary at all. This issue is about the intermediary server.
I will keep you updated on the progress. Thank you for your patience.
