Connection issues, unable to connect to a match

Whenever I connect to a match (any match, even training grounds) I have a chance of not loading into match and getting an error message, saying “Unable to connect to a match”. Every next attempt will result in an error message saying “Disconnected because of inactivity” or with a really low chance I will get into a match. Worst part is that this error could happen if I join training grounds and if I cant connect I’ll have to wait 13 minutes for match to end. Could playing on Ru region cause this error or is it persistent on any region?
