TF2 connects to the same community server over and over

Whenever I try to connect to a community server (from the list), I get connected not to the desired server but to the same server every time. The server looks barely legit, has players count corresponding to local time over the day, doesn't shove anything in the face. What the hell is going on?

This doesn't happen when I try to connect to official servers. As a temporary fix (until TF2 is restarted) this always works: connecting to any server by IP address and then connecting to community servers. I might have managed to "fix" it temporarily couple of times by messing around with server list, but not sure...

(Tried verifying game files, messing with server list settings, connecting in different ways, blacklisting servers. I get connected \*to the blacklisted server\*. Didn't run anything sus on PC recently.)
