Have same issue, cannot join Reforger servers. Connection worked correctly about two weeks ago, then problem suddenly appeared. Then it was fixed by itself but today I noticed that doesnot work again. Nothing helps, tried to reinststall mods, reinstall the game, change ISP. It doesnot work on my PC and Xbox. I am from Russia. I know that it is not content blocker because all my friends play normally. Also sometimes i am able to connect too. Please investigate and fix this issue:( will subscribe on this topic
