Myfritz port forwarding from https / external port 443

Hello,

i am trying to set up my alexa skill to controll smarthome.
I am using my myFritz domain to access Homeassistant remotely and want to avoid using any external services like duckdns.

Now my problem is, that the alexaskill needs for the access token url the myFritz url without any port / access on port 443 which is, if i understand that correctly, the standard for https.
in my Fritzbox config i have my domain: https://xxxxx.myfritz.net:44262
with port 44262 i can reach the fritzbox page but i also do it with no port / port443.

until now i wasnt able to find a solution that is working where i can forward external port 443 → internal port 8123

i would be verry happy for any suggestions and support.

thanks in advance
Michi

I have the same problem. Have you found a solution for this problem?

fritz support said that from outside the network 443 sould not lead anywhere so that should not be a problem. i did not trie it yet
the last time i was a bit stupid and hat another portforwarding to HA in parallel
