I have been running a personal webserver from home for a while now. Recently I haven't been able to access the sites externally. 

I updated my Fritz box to the latest firmware to see if that fixed it. But it has not; I am able to get access to SSH (external port 2222 to internal port 22) but I cannot get ports 80 or 443 to forward to an internal IP.

This was working about a month ago. When I scan for external ports the HTTP and HTTPS (80 and 443) are closed.

I was also moved from the $85/month plan to the $75/month at around the same time. I'm on unlimited fiber 100/20.
