Installation problem: "Client sent an HTTP request to an HTTPS server."

[arararar]

Hello out there,

i need a little help with installing, please!
i followed the instructions so far (https://github.com/nextcloud/all-in-one#how-to-use-this), i am using a fresh debian bullseye amd64 installation.
when i call "https://:8443 the certificate is imported correctly.
i use a dyndns for , updated via my fritz-box, ports 80, 8443 and 443 are forwarded to the debian outer system.
80 --> 80
443 --> 443
8443 --> 8443
but i get stuck at "new aio instance" with error message:

Domain does not point to this server or the reverse proxy is not configured correctly. See the mastercontainer logs for more details. ('sudo docker logs -f nextcloud-aio-mastercontainer')

and in the server console log:

[client 127.0.0.1:36976] The response of the connection attempt to "http://<server>:443" was: Client sent an HTTP request to an HTTPS server., referer: https://<server>:8443/containers

i replaced /etc/hostname and /etc/hosts-localhost entry with the dyndns domain-name .

what am i missing?!
is my port forwarding scheme wrong? should i use 443 --> 8443 instead e.g.?

Do you have an reverse proxy in between?

What is the startup command that you used?

Is something rewriting all access to your domain to a https connection?

Hi, thx for helping!!!
I did not configure any proxy, i only forwarded the ports.

Startup cmd was this the one given to install:
For x64 CPUs: sudo docker run -it \ --name nextcloud-aio-mastercontainer \ --restart always \ -p 80:80 \ -p 8080:8080 \ -p 8443:8443 \ --volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config \ --volume /var/run/docker.sock:/var/run/docker.sock:ro \ nextcloud/all-in-one:latest

Your last hint - i dont understand your question. ?
