How to use Traefik reverse proxy with Nextcloud AIO?

[iamnikv]

I am following the guide for setting up Traefik and the command for running the docker container:

For x64 CPUs:

sudo docker run -it
--name nextcloud-aio-mastercontainer
--restart always
-p 8080:8080
-e APACHE_PORT=11000
--volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config
--volume /var/run/docker.sock:/var/run/docker.sock:ro
nextcloud/all-in-one:latest

However when I get to here:

.. and enter my domain name I get this error:

From the Traefik container:

On the Nextcloud VM:

Traefik config:

Hi, can you run nc -z <yourvalue> 11000 again from the traefik container with this value?

[szaimen]

And echo $?
Of that?

[iamnikv]

[szaimen]

Please run the nc -z command first and afterwards the echo $? command

[iamnikv]

Like this?

[szaimen]

Yes. Looks good.

I see what the problem is. Did you open port 443 in your firewall and router?

[iamnikv]

I have opened port 443 but for the VM that hosts the Traefik container. Should I open it for the Nextcloud VM as well?

I don't understand. How can you open the same port mutiple times?

[szaimen]

Also is your domain correctly set up that you want to use for Nextcloud and does it point to your server?

[iamnikv]

I think it is correctly setup because I am using it for my other services and I can access them from outside of my local network by the domain name.

[szaimen]

The subdomain as well?

[iamnikv]

Ok I am dumb. I was pointing the domain name in the router config to the local ip of the Nextcloud VM instead of pointing it to the VM hosting the Traefik container. I changed it and not it works :)
Sorry for the all of this and thank you for pointing me to the problem :)

[szaimen]

Great that you found the problem!

[szaimen]

Btw, did you see this?

[szaimen]

Just asking because your traefik config looks pretty different

[iamnikv]

Yes, I saw it and I compared the headers. Most of the I had already included. I had missing these two:
hostsProxyHeaders = ["X-Forwarded-Host"]
X-Robots-Tag = "none"
But wanted to see if it would work without them and it does.

For anyone who is trying to setup Traefik as reverse proxy I would like to link them to the guide I used for setting it up and it works really well for me. It the one from TechnoTim: https://techno-tim.github.io/posts/traefik-portainer-ssl/
