Can't get in game server list to work


Staff member
After reformatting my computer I cannot get the ingame server list to work.
I did double check my router settings and it seems all fine.
TF2 server list works, and so is the steam server list.
Only server list that doesn't work for me is the counter strike source.
Any ideas?
This happens to me every 5 months or so. When you try to join does it say 'failed after 4 retrys'? I think it has something to do with steam not connecting to you but this will usually last 2-3 days
