Hi, so I did a completely fresh install of HAOS last night and installed the duckdns addon (including setting up the duckdns domain and generating certificate). Unfortunately, every time I try to connect to my server through SSL, I get SSL_ERROR_RX_RECORD_TOO_LONG (firefox) / ERR_SSL_PROTOCOL_ERROR (chrome). It works fine through http. I have forwarded 443 to 8123 and 8123 to 8123. There is no indication anywhere that anything is working incorrectly. My router supports hairpinning so I do not understand why this is not working. SSL in general (not home assistant related) works fine. The SSL folder has both the privkey and fullchain files. I can ping myself just fine through the duckdns domain (it resolves to my ip). I spent about 6hours perusing google to no avail. Hopefully someone can help?
DuckDNS log with my domain and IP edited out and replaced with "mydomain" and "myip" for privacy reasons.
