Description

I am trying to do following the issue #9587 and https://docs.firefly-iii.org/references/faq/install/#how-do-i-set-tls-in-firefly-iii-or-the-data-importer but still not working for me.
My Request chain is Webbrowser(443) -> Cloudflare(80) -> nginx(80) -> firefly
When I enabled the TLS, not all requests were changed to https. Some URL schemas are still HTTP, not HTTPS.
The Config parameters APP_URL have been set to HTTPS:// instead of HTTP://,TRUSTED_PROXIES=**

Hi, thanks for starting a discussion!

This happens often with Cloudflare. I believe they rewrite URLs so it's difficult to spot broken configurations. They rewrite the <a href= tags, but nothing else.

If proxy_set_header X-Forwarded-Proto $scheme; doesn't do the trick then I'm not sure what the solution could be though.

Yes. you are right. it works when I disable Cloudflare. Thanks for your help.

I found the reason when I changed the Cloudflare proxy mode from Flexible to Full. this issue has been fixed.
