Caddy with Jellyfin creates an error when i try to watch a movie

Help
1

1. The problem I’m having:

Hi !
First, i would like to point out that I am a beginner in these type of things.

I am trying to set a proxy for my media server (jellyfin). My current server has a domain name with no Ip. I managed to create the proxy and access jellyfin on my server with HTTPS but when i try to listen to a media, it keeps loading and i receive non-stop errors on my server.

2. Error messages and/or full log output:

2023/03/25 04:20:24.897 ERROR   http.handlers.reverse_proxy     aborting with incomplete response       {"error": "context canceled"}
2023/03/25 04:20:24.972 ERROR   http.handlers.reverse_proxy     aborting with incomplete response       {"error": "http2: stream closed"}

3. Caddy version:

v2.6.4

4. How I installed and ran Caddy:

I installed Caddy with the official installation methods.

a. System environment:

UbuntuServer 22.04 (not in a docker)

b. Command:

cd /var/lib
caddy start

c. Service/unit/compose file:

d. My complete Caddy config:

gonpass.ddns.net {
        reverse_proxy 127.0.0.1:8096
}

5. Links to relevant resources:

I strongly recommend running Caddy as a systemd service. If you installed Caddy using our apt repo, that should be set up for you already.

Using caddy start should only be used for quick-and-dirty development tasks, not for a long-running Caddy instance.

Can you check Jellyfin’s logs? It might reveal the problem.

I run Jellyfin and I don’t have that problem myself.

3

I tried starting caddy with systemctl but here’s the logs. I’m not quite sure what i should put in the config file and how to use the Caddyfile i used.

4

Your Caddyfile syntax is invalid. You have a colon where there shouldn’t be one.

First I’d like to thank you for your help !

I fixed the config file and started the service, but just like last time. I can access the website on https but when i try to watch a movie i keep getting the same error. I’ll put bellow my config file, the status of the service and the error I’m getting.

gonpass.ddns.net {

        # Another common task is to set up a reverse proxy:
        reverse_proxy localhost:8096

        # Or serve a PHP site through php-fpm:
        # php_fastcgi localhost:9000
}

Remove this stuff from your config, it’s not useful. That’s just meant to act as a basic example of what you can do with the Caddyfile, you shouldn’t leave it in when you write your own config.

:point_up: did you look at your Jellyfin logs?

I’ll put bellow the logs created when i start the service and the first log that comes out when i access the proxy to listen to a movie

Those are your Caddy logs. I mean your logs from Jellyfin itself.

Oh my bad, here are the logs when i connect to jellyfin and try to open a movie

Do you believe the cause of my issue could be in my jellyfin config because i have not seen a similar issue with jellyin and caddy online.

11

I guess a couple things you could try is these two options for reverse_proxy – try them separately and see if either of them changes the behaviour:

flush_interval -1

OR

transport http {
	versions 1.1
}
12

I tried both and here are the results

Transport :

 Error: adapting config using caddyfile: /etc/caddy/Caddyfile:23: unrecognized directive: versions

        # Set this path to your site's directory.

        # Another common task is to set up a reverse proxy:

        # Or serve a PHP site through php-fpm:
        # php_fastcgi localhost:9000
}
transport http {
        versions 1.1
}

Flush_interval ( The service started but got the same result as before )

}
flush_interval -1
13

Those are subdirectives of reverse_proxy. See how the Caddyfile is structured: Caddyfile Concepts — Caddy Documentation

Try this:

gonpass.ddns.net {
	reverse_proxy localhost:8096 {
		flush_interval -1
	}
}

gonpass.ddns.net {
	reverse_proxy localhost:8096 {
		transport http {
			versions 1.1
		}
	}
}

Make sense, sorry about that. Unfortunately I got the same error as before for both

 {"level":"error","ts":1680297803.0358062,"logger":"http.handlers.reverse_proxy","msg":"aborting with incomplete response","error":"http2: stream closed"}
15

@gonpass I also proxy Jellyfin but with no problems. What client/browser are you using that is resulting in this error?

16

I’ve tried edge and google chrome and both resulted in the same error unfortnuately.

17

Huh. I usually use Firefox so I just tried it with Chrome including from a different machine (so it goes over a network) and it worked fine for me. :man_shrugging: My config is identical to yours in the first post in this topic.

What’s your network topology like?

PS. Is this for videos or just audio? I tried video. The title says “watch a movie” but the post says “listen” so I want to be sure.

18

yeah sorry about the confusion, i mean watching a movie.

I’m not quite sure what my topology is but from what i read online i believe I have a regular star stopology. My server is connected to a router where i do a port forwarding in order to access my server from outside the LAN.

Ok, good to know. Does the error happen when you’re inside your network? Outside the network? What about from the mobile app? (Try toggling your phone’s wifi for a quick switch between internal and external access.)

I suspect something in the middle is disrupting the connection.

20

So i tried on my phone with the application and it strangely worked when i was connected to the wifi and when i wasn’t. But I did get an error

Apr 02 21:18:55 benserver caddy[20629]: {"level":"error","ts":1680470335.6094565,"logger":"http.handlers.reverse_proxy","msg":"aborting with incomplete response","error":"write tcp 10.0.0.35:443->204.48.93.50>

What i found out is that my app that controls the port forwarding believes that my server has the ip 10.0.0.35 but that’s not the actual ip address. When i went into my router’s settings i could see there my actual ip address connected to the server. I don’t know if it changes anything but i wanted to point it out just in case.

ps: Even tough the app believes the ip address is 10.0.0.35 the request does get redirected to the server
