On CLWHost Unturned servers, the server password should normally be changed from the Wisp Startup tab.
Our Unturned egg passes the password into the server startup command, so you usually do not need to manually add a Password line to Commands.dat.
After restart, players will need the password to join.
The server should then be public again, unless other access restrictions have been added.
For CLWHost Unturned servers, use the Wisp Startup tab first. This keeps your settings in line with the egg.
Only use Commands.dat for password settings if CLWHost support specifically asks you to.
Contact CLWHost support and we can check the server settings for you.
