Hello, I’ve setup a FiveM server on my home computer and, while it works when connecting with localhost, it doesn’t work when trying to use my public IP address. I’ve already setup port forwarding in my router config. I’ve tried checking canyouseeme.org and it says: Success: I can see your service on 151.51.53.41 on port ( 30120 )
Your ISP is not blocking port 30120.
I also use the same machine (with same IP) as web and SSH server and they both work, so it should not be a connection or configuration problem.
So I don’t think it’s a problem on my end, but there has to be something wrong with FiveM. Anyway, I’m open to suggestion because that’s driving me crazy.
