Garry's Mod 3.9.15 Update

here is the ink for the new Garry’s Mod update.

Could anyone help me to update my server?

It says to restart the server, but after doing so on connecting it says “The server you are trying to connect to is running an older version of the game.”

Like I said on your other post, use SteamCMD:

Thank you!

for other people

Shut server down.
In control panel select “Steam Update”
allow to finish until “Process Complete”
