Port forwarding stopped working

I've had port 8123 forwarded and working fine for the past few years. Something changed two days ago. The service is still active and online on the internal IP, and I have set up port forwarding for port 8123 for my router, but I simply cannot reach it when visiting the external IP and the port number. Nothing has changed on my end.

I spent 45 minutes on the phone with an Xfinity support agent who obviously didnt even understand the problem I was explaining, and was not helpful in escalating me to an actual engineer.

I have found several related issues here with no helpful responses:



I just set up a separate Raspberry Pi server on port 8000 to test. I created a new port forward for port 8000 linked to that device in the Xfinity app. No luck, even with a brand new server and brand new port forward.

Has anyone encountered this and been able to resolve it themselves? It doesnt seem like Xfinity knows whats up.

I will share an update here when I have something tangible - I was just told it was some kind of outage that started last week. They couldnt tell me much about it, only that I will supposedly get a call back when it's fixed. No timeline given or anything like that.
