For goodness sakes, I’ve been eyeing your other thread, it’s clearly one of your addons or gamemodes, uninstall all of them and test a vanilla garry’s mod server.
I always find it funny, I’ve updated my server 3 times yesterday and the day before because First the CSS update, Then Gmod and then TF2 And DoD i think it was, My gmod just updated thuough steam, And me and my friends are have no problems at all playing on my server. Why can’t people with problems just run the updater once?
As far as I can tell, the solution has already been posted in this thread.
What they want you to do is remove all your addons to narrow down what is causing your server not to work. If your server still refuses to work even on vanilla (or near-vanilla) GarrysMod, we’re a little bit closer to finding the solution.
More than likely the issue is he’s running a (leaked) custom gamemode that uses modules that need to be update. The official policy on support for leaked gamemodes is
“how am i supposed to update something that was leaked?”
this is not a “leaked gamemode” this is a custom gamemode I bought from the original coder. What you’re telling me, because of the update, I need to contact the original coder (which I will probably have to pay money for) and have him “update” the gamemode?
