(TF2) Weird problem that just popped up for a few users including me

[RingmasterJ5]

So, for the past few days, I've been running a private TF2 server for MVM. Everything was going amazing...until last night. Suddenly, my server was LAN-only. Nothing was changed, and from a few other threads on the Steam forums, it looks like I'm not the only one with this problem.

Code:

66.7 fps  0/32 on map        mvm_decoy
Console initialized.
Game.dll loaded for "Team Fortress"
maxplayers set to 32
No '-replayserverdir' parameter found - using default replay folder.

And, when I join the server, this is in the in-game console:

Quote:WARNING: Port 27015 was unavailable - bound to port 27016 instead
WARNING: Port 27005 was unavailable - bound to port 27006 instead

Thinking this was the problem, I rechecked the ports. Nothing was different, the same configuration I used when it was working was still there:



How can I fix this?
