Domain using a Cloudflare Tunnel doesn't work

[jeypawlik]

What are you trying to do?

I bought a domain for all my NAS/docker containers, using Cloudflare I made a tunnel and set a subdomain to each docker container's local address. I made "grimmory.website.com" to access Grimmory while I'm out of my home network.

What's happening instead?

I can access my Grimmory pages, shelves, librarys, metadata, but cannot open books while using my domain. When I try to open a book it just loads forever. It works fine on my local IP address.

I've tested all my other docker containers and none of them have any issue like this, so I'm wondering if I'm just missing a setup or step somewhere with accessing Grimmory's database outside my network? The Grimmory docs only mention Cloudflare tunnels once and it didn't help my issue. I'm very very new to docker and containers so it's very likely I just missed something very obvious.

Your setup

Version: Release v3.2.4 (latest)
Docker
Ugreen NAS

Anything else that might help?

Okay an addition as I've been testing this issue out, it looks like PDFs specifically aren't working through the Cloudflare tunnel, .cbz, epub, and MOBI all seem to be working just fine. Audiobooks are a little hit or miss, but have been loading for me the last hour or so.

Wondering why this is just effecting PDFs?

I have no issues with PDFs (or any other book/audio format). Maybe a networking timeout issue?

I've honestly tried so many things, but ended up making a proper issue post regarding my findings with PDFs and Cloudflare.

Are you also using a Cloudflare tunnel for your Grimmory?

[rubengarciam]

Yep

I use zero trust tunnel too and just tested a pdf book. Looks fine for me

GUH! I'm sorry everyone, it's been a frustrating few weeks but the fix was to just delete the tunnel to Grimmory and recreate it. I can't believe it! It's strange that only PDFs weren't working, which was why I suspected something else was afoot, but hearing everyone else not having an issue with their tunnels made me question the tunnel itself.

Thanks for your help y'all!
