No lobbies found
The current issue list says some players can be region locked and unable to see other lobbies. This does not by itself show that your router is blocking the game.
Multiplayer status
Patch 0.34.23 lists a region-lock issue that can prevent some players from seeing other lobbies. An earlier 0.34.19 snapshot also documented no-lobby results and Steam-invite trouble. First confirm that every player is on the current build before changing network settings.
Field note
The current issue list says some players can be region locked and unable to see other lobbies. This does not by itself show that your router is blocking the game.
Joining through a Steam invite appeared in the earlier 0.34.19 issue snapshot; check newer notes before assuming it remains unchanged.
Checking that the whole group is updated is a sensible diagnostic because different builds cannot be assumed compatible. This is general troubleshooting, not a cited root cause.
Field note
The official source establishes the symptoms. These steps are general Steam session checks and are labeled accordingly.
Look for a current developer update or widespread reports before changing local settings.
As a general check, verify that each player appears online in Steam and that no game update is pending.
Close the game, restart Steam, and create a fresh lobby or invite. This refreshes the client session but does not repair a server-side defect.
Use a fresh Steam friend invite and have the recipient accept it from the normal Steam interface or overlay.
Try with one host and one guest first. Record whether lobby discovery or the invite path fails, along with the current patch number.
Field note
If multiple players on different connections see the same failure, keep the evidence short and check the official discussion. A reproducible report is more useful than stacking unrelated network changes.
