https dyndsns error after bullseye upgrade

Hello,
just upgrade to bullseye with this https://dietpi.com/blog/?p=811 instruction.
the nginx webpages are not available with
https://mydydns/nextcloud anymore, but only with http://currentip/nextcloud. nextcloud is accessable.
http://currentip/wiki is still redirecting to https://mydyndns/wiki and is not accessable
http://localip/nextcloud works
http://localip/wiki is redirecting to https://mydyndns/wiki

any ideas how to go on?
Regards droogi
btw the webfinger / node misconfigure info is gone…

did you tried to access your web site using https and your external IP? Did you verified your external IP is correctly set on your DDNS provider?

Hello Joulinar,

today i used my router for updating noip, all webpages work now with http:, but not with https
i checked only externaly so far, not within my local network.
(nextcloud, wiki, tasmoadmin, phpmyadmin)

(I think i was running noip on the buster installation, and lost it during update to bullseye).
Regards, droogi

does the web server is listen on port 443 still?

ss -tulpn | grep LISTEN

No port 443 anymore

yeah in this case HTTPS is not working anymore :sunglasses:

did you tried to recreate SSL certificate using dietpi-letsencrypt?

thank you for the hints,
i reinstalled the certificates and everything works as it should.
