so i tried to play it with some friends but i  couldn't get it to work when the host starts the game i get this message

i searched for a solution but nothing worked for me, i verified the integrity of the game and deleted the two files "materials" and "models".
i was wondering if someone can help me with this.

edit:
I also found this reddit post about it
https://www.reddit.com/r/GlobalOffensive...h_friends/
i had the same probleme when i tried to play it with 2  3 different people.
even after restarting the game the samething happend.

If possible: try and see if people on your local network can join the game if you have the option.
In windows, open cmd, and type ipconfig
Keep note of your IPv4 address
let the other person type in console: "connect 192.168.xxx.xxx", where xxx.xxx should be replaced with what is in your actual IPv4 adress.
It may or may not be possible to open up the server to people outside your LAN, I'm not entirely sure how CS:GO handles this, but you may need to port forward a port. I'll do some testing and get back to you :-D
