Use sv_offline 1 to hide it on the server list.

Because they are not sorry that they cheated, they are sorry that they got caught.

IIRIC that router has a ddos protection you should turn off.

Try using the Event Viewer of Windows to figure out a reason.
Also post a screenshot of your game folder and the zone folder inside of it.

Sounds a bit like your router is too weak to handle all the connections from the queries.

sv_offline set to 1 will get rid of those messages and won't announce your server to the master.
This way you can test if its the additional load by it being public.

You are behind a CG-NAT, while the IP you used to post this is not blacklisted by any API IW4mA uses a different IP you used on this forum is blacklisted.

You could try and see if you can turn this off in the webportal of your ISP.

Also actual specs are required, what you posted is used to scam kids out of their pocket money.

I cant find a menu that works, and I don't want to do it if its a bannable offence.

And if you find one that works the anticheat will ban you. Bots in IW5 won't do anything at all and are totally useless. Also you can ignore 100% of what OneTap wrote as he did not bother to check in which section this thread is in.

Try verifying the game install via Steam.

OneTap said in How to put a single map on your zombie server:

I only have one map it's Buried, I put its -> sv_maprotation "gametype zclassic loc processing map zm_buried"

Leave it like that and ignore whatever you have found.

Compiled GSC files do not contain anything that would them not work on a different PC.

How much are you paying to use piry again?

No, old school debugging only.
