My Home IP address suddenly became unreachable?

I'm running a small website on my IP (IPv4) address. Suddenly, since last night, nobody could establish a new connection to my IP, they get a connection timeout. This is despite my internet seemingly functioning normally. I can reach all the ports internally from my LAN Until last night, I could reach the port from the internet I've tried a traceroute, it never reaches my IP address. 19 lag-1.hcr01bflomnar.netops.charter.com (96.34.22.167) 83.603 ms 83.720 ms 83.599 ms 20 lag-10.hcr02bflomnar.netops.charter.com (96.34.22.127) 83.422 ms 83.420 ms 83.439 ms 21 lag-18.bflomnar02h.netops.charter.c
