Unable to connect to jellyfin and mattermost from android apps

zeromancer · February 13, 2023, 12:27am

Hello,
im using traefik 2.9.6 with docker/portainer with letsencrypt certificates. Im struggling for a while to connect jellyfin via the android app to my homeserver. Today i set up a instance of mattermost and i got a simmilar connection issue. I can reach both via the browser app from outside my network on the android phone without any problems. Do i need any special configuration to connect android apps?

http:
  routers:
    jellyfin:
      entrypoints:
        - "websecure"
      rule: "Host(`xxx.xxx.duckdns.org`)"
      tls:
        certResolver: production
      service: jellyfin
    mattermost:
      entrypoints:
        - "websecure"
      rule: "Host(`xxx.xxx.duckdns.org`)"
      tls:
        certResolver: production
      service: mattermost

    jellyfin:
      loadBalancer:
        servers:
          - url: "http://192.168.xx.xx:xx"
        passHostHeader: true
    mattermost:
      loadBalancer:
        servers:
          - url: "http://192.168.xx.xx:xx"
        passHostHeader: true

Im pretty new to traefik and to this forum, don't hit me to hard please.

Enable Traefik debug log and access log. Check debug in general and both during access of your app.

Im sorry but im not really able to read this, I hope someone can help me out.

Can you try to get debug (not only error) and access log for the same request (at the exact same time)?
(When you don't enable writing to log-file for both logs, you will get the combined output in the container log.)

Can you also check the (debug?) logs of the target service for the same request?

There is no general .log written while the connection attempt happens.

The access.log still says:

What do you mean by target service? Im not able to debug the mattermost app in my setup atm.

The Android app seems to do a HTTP HEAD request and you get a status 405 back.

405 Method Not Allowed

But to me it`s not clear if that comes from Traefik or your mattermost server.

In the Traefik docs HEAD is mentioned, so I would assume it is just passed on to the target service.

Rule `Method(`GET`, ...)`
Check if the request method is one of the given methods (GET, POST, PUT, DELETE, PATCH, HEAD)

Therefore I recommend to check the logs of your target service.

Could it be, that the redirection from http requests to https is messing it up?
I do:

entryPoints:
  web:
    address: :80
    # (Optional) Redirect to HTTPS
    # ---
    http:
      redirections:
        entryPoint:
          to: websecure
          scheme: https

  websecure:
    address: :443

Should i allow the http?

As I sayed, im not able to debug the app on my phone.

##EDIT##
Same "fault" after I removed the redirection.

I mean debug mattermost server to see if it receives any forwarded requests from the Android device.

I can connect via ip. The mattermost log says:

{"timestamp":"2023-02-13 13:34:47.240 Z","level":"info","msg":"api endpoint requires a license","caller":"web/context.go:115","path":"/api/v4/users/ok8ptgudf8sdfn3wg6x64sgf9o/groups","request_id":"cy1rxi3nbb9sdfasdjpqdus75h","ip_addr":"192.168.xxx.xxx","user_id":"ok8ptgu7asdfa87wg6x64sgf9o","method":"GET","err_where":"","http_code":501,"error":": api endpoint requires a license"}

If i try to connect via URL, nothing in the mattermost log.

Mattermost log is in DEBUG as well.

####EDIT####
It worked once. After reopening the app the server is unreachable.
###########
I don't know what exactly the problem was but i solved it by changing the Listen Address in Mattermost from:
127.0.0.1:8065
to:
*192.168.0.69:8065 <- IP Address from the Server *

Thank you for your help, i learned a lot about logging today!

Workaround:
Using Nginx Proxy Manager.
No additional setup needed.
