Trouble finding servers - fix
I had this issue and I know there are others who are able to find servers but only barely. We see about 10 servers and then lose all them after refresh, at which point we need to wait some time before seeing the servers again.
The fix for this issue, which might manifest itself in other steam games as well, is to go to (in steam)
steam > settings > downloads + cloud tab and change the value of Game server browser: max pings /minute
The reason I posted this is that I haven’t seen this fix anywhere other than through an obscure search, as a small portion of some steam news update
