[Need Help] Attempt to decode JSON with unexpected mimetype: text/html', url=URL('....')

[ghost]

Hey!

I'm getting this error when using your lovely software:

Output from the log.log: https://paste.ec/paste/jmH-GoOH#qetLghapEmczdLcCZ1uFzeSBaAQ8T7xaa7yHzjxjfFT

I'm running it in docker.

My docker-compose.yml setup:

version: "3.9"

services:
  jellyplexwatched:
    container_name: jellyplexwatched
    image: luigi311/jellyplex-watched:latest
    labels:
     - "org.hotio.pullio.notify=true"
     - "org.hotio.pullio.update=true"
     - "org.hotio.pullio.generic.webhook=https://notifiarr.com/api/v1/notification/pullio/xxxxx-xxxx-xxxx-xxxx-xxxxxxxxx"
     - "autoheal=true"
    volumes:
      - /opt/docker-all/jellyplexwatched/config.env:/app/.env
      - /etc/localtime:/etc/localtime:ro
    restart: unless-stopped

My config.env (with URLs etc redacted): https://paste.ec/paste/V0p7h0Fa#4QWxivibZG60U8eM1EDRLyn8j5QEC7KC17+j44upsfi

My NGINX file for my jellyfin.domain.com, if that matters at all. I'm just using the official nginx reverse proxy from the jellyfin docs: https://paste.ec/paste/mLYMPSIM#vUgW46tgSt59ACOIffnI9arMq8OjKoGZ7TTnXHxje9k

This also appears in the log, if the docker container just stays open:

Just FYI, I can connect and use Jellyfin just fine.

The entire log, from letting it run a few hours: https://paste.ec/paste/ggW+0ndX#9ny0csbX6OwE4En6V+EOusWxeNYfsYuFKHNSdMrtWl5

Can you try the dev branch and see what it says. I add in a check for response status of 200 and if not it will output what the server responded for the status code and reason. It should give you some more information on whats going wrong.

Thank you!

I think I solved it. It was a 504 Timeout Error.

So I increased the timeout in the jellyfin.domain.com.conf file in my NGINX sites-available folder. Added this in all the /location blocks:

  proxy_connect_timeout       600;
  proxy_send_timeout          600;
  proxy_read_timeout          600;

This didn't seem to have much of an effect.

I tried changing my server's DNS Nameserver as well, which seemingly did the trick. Before it was using Hetzner's DNS Nameservers. I changed them to the 1.1.1.1 DNS Nameservers, and now it seems to work.

So thanks for adding a "response" the error, so that I could do some troubleshooting.
