Cannot find Assetto Corsa Competizione server
Make sure to select ‘Server Type’ : ALL, paste server code (not password) into Search box and click on ‘Refresh List’.
Main server issues
Sometimes ACC main server list is down, and so no servers at all will load/show in ACC server list. Unfortunately we have no control over this, but you can check this page, if and when it is down:

Missing DLC
We also noticed that server might not show due to missing DLC even if 'Accessible' filter is turned off. Check event info page if the track requires DLC and verify that you have it installed in Steam (Library > Assetto Corsa Competizione).
