What Could Cause This?

I have played officials now for about 2 years and i have always had the problem of only 100-200 official servers show up without any filters. Because ofGAME SERVERShave always used Battlemetrics to connect to the servers that i play on but now for some reason connecting trough it or steam it says "server is full" even though it's not so i now have to use the server list and even if it didn't say that the server is full i still have to use the session list of the game to transfer across different maps. Sometimes it doesn't find any servers and sometimes maybe 20 when i filter a certain map, after refreshing 10's or even 100's of times it might find the server that im looking for but it takes a lot of time when i have to refresh many times every time im joining a map or going from map to map. I have reinstalled windows, steam and ark again and it hasn't helped. What could cause this?
