Play movies under nginx proxy sometimes lag

[caoli5288]

Describe the bug
When I streaming with reverse proxied url, the movie opens very slowly, gets stuck once in a while. And I can see some bad logs.

[01:07:15] [WRN] HTTP Response 206 to 192.168.2.148. Time (slow): 0:00:11.9331747. http://192.168.2.148/emby/Videos/6991382334f2b68c30d08e7fa9e0c380/stream.mp4?Static=true&mediaSourceId=6991382334f2b68c30d08e7fa9e0c380&deviceId=TW96aWxsYS81LjAgKFdpbmRvd3MgTlQgMTAuMDsgV2luNjQ7IHg2NDsgcnY6NjAuMCkgR2Vja28vMjAxMDAxMDEgRmlyZWZveC82MC4wfDE1NjY1NzM0NjA4Mjk1&Tag=0c842a5f97531f275c7d939359cb3595

I installed jellyfin by docker run jellyfin:latest and config nginx like that.

    location /movies {
        return 302 $scheme://$host/movies/;
    }

    location /movies/ {
        # Proxy main Jellyfin traffic
        # The / at the end is significant.
        proxy_pass http://127.0.0.1:8096/;

        proxy_pass_request_headers on;

        proxy_set_header Host $host;

        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Host $http_host;

        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $http_connection;
    }

None of these problems exist when I access port 8096 directly. What should I do?
What else do I need to provide?

Hey,
so you access Jellyfin under the subdomain /movies? Is subdomain already supported by Jellyfin?

Best regards,
Jonas

@onny I follow this docs https://jellyfin.readthedocs.io/en/latest/administrator-docs/reverse-proxy/#nginx-with-subpath

Do you see any "slow movies" when accessing directly (not via nginx)? On the same connection, that is.
Also, anything funny in nginx logs?

[caoli5288]

@JustAMan No "slow movies" while accessing directly.
and seems not anything funny in the nginx log.

[JustAMan]

My wild guess here would be nginx trying to buffer something it shouldn't, that's why I asked about logs. I suggest you trying to disable buffering in nginx and see if it helps.

[caoli5288]

@JustAMan
I follow this docs. Seems no buffer enabled.

Is this official docs?

[JustAMan]

That one is the previous version, we moved docs.
See proxy_buffering off; in the up-to-date version: https://jellyfin.org/docs/general/administration/reverse-proxy.html#nginx

[caoli5288]

@JustAMan THX. I'll try it next days.

[caoli5288]

@JustAMan Solved. THX

[JustAMan]

Could you please describe what helped you here, turning buffer off? For others' reference.
And if you no longer have the problem please close the issue. Thanks :)

[caoli5288]

@JustAMan I add proxy_buffering off;. So you may needs to update documents under Nginx with subpath section. :)

[JustAMan]

@caoli5288 please verify the docs issue I made. I'm going to close this issue as I see it's fixed.
