Access my IPv6 hassio from IPv4 addresses


my ISP only provides an IPv6 address and I got SSL with the NGINX Proxy Manager running.

I had a few problems over the last months accessing my hassio, because the mobile carriers in other countries do not have IPv6 enabled, also in a lot of hotel/airport wifis there is only IPv4.

I tried now with an portmapper to access my hassio.
I do get an connection to the webinterface, but since its not a SSL connection, I’m not possible to login.

My current configuration looks like this:
own domainname “” with an AAAA record to my hassio
NGINX Proxy Manager Host from “” to local hassio IPv4 “” with an Let’s Encrypt Certificate.

Do you have any ideas how I could create an Let’s Encrypt Certificate, so I’m able to login?
