Tachiyomi - kavita extension. Not working behind a Reverse Proxy / Clouflare DNS

[itadna]

Describe the bug

Sitting Kavita behind a NGINX Proxy on Cloudflare DNS, the Tachiyomi extension stops working. The OPDS still works because it is ok via webview, via web browser and other apps like moon reader & co.
The error claimed by Tachiyomi is regarding a strange Kavita version mismatch: "v0.5+ is required". I'm on 0.7.10.2.
Setting everything to the original address:port system, everything works again,
https://111.111.111.111:5000 OK
https://kavita.name.dom:5000 OK
https://kavita.name.dom NO

To Reproduce

Steps to reproduce the behavior:
Set Kavita behind a reverse proxy in order to hide the port from the address
Generete an opds key in kavita
Import the opds key/address in tachyomi (kavita extension)
Browse the source
Error: kavita version mismatch

Expected behavior
The content of your library should be shown.

Additional context

Pointing directly to the opds address (in the format without port 5000 at the end) you can correctly download the odps manifest (as attached).

Thx. I have exactly the same problem. Hope this will be fixed soon

Ran into the same issue and for me it was because Kavita defaults to a http opds url, while I configured my domain to be https only. Changed the url scheme to https and that allowed Mihon to connect to Kavita.
