Hi @Mike9817

simple question:

Isn’t it possible that you use the integrated self signed certificate?

I use my Fritzbox with that certificate.

Valid until 15.1.2038

So I don’t need any renew. Only a browser exception.

CERT von der Fritzbox a the Browser is firefox
sorry it was from DynDNS, when i buy the fritzbox it was the zertifikat from letsencrypt. My mistake was that i changed is. Know i want get an new zertifikat from Lets encryt. is it possible?
Thanks

Don’t know how the cable version works.

But it should be always the same.

System - FritzBox User - Create a user and add “Internet Access”.
Internet - MyFritz!-Konto / Account: Activate “Internet Access”, use the Letsencrypt certificate.

Then you have a random address

awbcuxowembxus.myfritz.net

with a random port.

PS: Because it’s a myfritz.net address, Fritz is able to create a Letsencrypt certificate and should renew it.
