Cannot seek further in videos using the player time bar

Help
1

1. The problem I’m having:

I cannot go further in any video on any player (I tried the simple player on mobile/desktop Edge, Kodi). When I click or tap further on the search bar, it sends me be back to the beginning of the video on Edge and on Kodi (Nvidia Shield TV) the player exits.

I didn’t observe that issue when I was using webfs.

Would you have any idea on how to solve this?
Thank you.

No idea. I suggest you search the internet for more leads, because this doesn’t seem like a Caddy-specific issue at a glance. We’d need more evidence (debug logs, etc) to have some leads.

Hello, thank you for your reply. Would you know if Caddy supports byte range requests? A feature to allow skipping to another position in a streamed video in the provided file server?
I’ve searched online but cannot find any lead.
Thank you.

There’s no reason why Caddy wouldn’t support it. We proxy the headers as-is to the upstream.

Again, not much we can do to help without debug logs and more evidence, like example curl -v commands showing the behaviour.

Edit: oh sorry I didn’t reread your original post after seeing your reply so I didn’t realize you’re using file_server instead of proxying. So scratch that part.

Still though, evidence is needed.

I just played around with it just for my own info; it works fine. I’m playing an .mp4 served from file_server, with basicauth enabled, and I can skip around in the video with no trouble, on both Chrome and Firefox. Turning on the log directive, I see Content-Range response headers corresponding to the points in the video I skipped to, every time I click in the scrubber bar.

Hello Francis, thanks again for your help. It seems this is an issue with Cloudflare not transmitting the “accept-ranges” header properly. webfs, that used to work fine with byte ranges, stopped working as well. I think I’ll give up.
Thanks for your time.

You can turn off Cloudflare’s proxying by setting it to the “grey cloud” mode. That should fix it.
