steam://connect/<ip>:<QueryPort>
steam://connect/<ip>:<QueryPort>?appid=440900
steam://connect/<ip>:<GamePort>
steam://connect/<ip>:<GamePort>?appid=440900

[Methods tried]

In Steam >View > Game Servers > Right click on any server > Copy link to clipboard
Gives me the link with ?appid=<id> out

steam://connect/<ip>:<QueryPort>
steam://connect/<ip>:<QueryPort>?appid=440900
steam://connect/<ip>:<GamePort>
steam://connect/<ip>:<GamePort>?appid=440900

Is there a solution to this problem? Since no more direct join links work!

440900 is a mod directory
Try disabling your Mods one at a time.
You may need to manually update Mods or uninstall outdated ones.

And because It’s a private server, the Server Admin may need to do the same to find the Mod causing the Issue.
