TF2 dedicated server issue with GSLT

[「Zan」]

So I used to host a couple of servers from home for a good while, until some time back they stopped working in the sense that they could no longer be connected to outside the network. Same port forward settings and everything. What I have so far boiled the potential issue down to is when looking at the logs on a fresh SRCDS install, the log shows "sv_registration_successful = 0" followed by "sv_registration_message = no account specified", and using the API call it shows the gmsindex as -1. What could cause this?

Have you tried running the server with a GSLT?
I'm not sure that this is your issue though. From what I remember you only need a GSLT if you want your server to act like an official one. For example I still have an old private MvM server running without a GSLT and can still connect fine. And this server is showing gmsindex as -1 also. However this server is connected to the internet with a public IP and not behind a private network like yours.
I would check if using a GSLT makes it work. If not it's most likely a port forward or firewall issue.

The issue stated above is with a GSLT, and the reason I used one is so my server stays in peoples favorites even when the IP changes. As said, it used to work just fine, then suddenly the server became the way it is now, unable to be connected to outside the network.

I have found the issue and fixed it, had to do with my connections APN setting having reset itself. Changed it back to the correct one and it works now.
