Error saving bookmark: Request Error: - Linkding via Cloudflare Tunnel

[ntwkrgr]

When attempting to save a bookmark, about 1/3 of the time I'll get this error: Error saving bookmark: Request error:

I'm running Linkding in a Docker container on a local RPi4, accessible anywhere via a Cloudflare tunnel.

Cloudflare is configured to use http://local IP for RPi4:9090 to access Linkding, which works for accessing the page itself, and has successfully saved some bookmarks via the extension.

I found this issue from a year ago that mentions http/https potentially being the issue, but I'm unable to get Linkding to work using anything other than http:// in Cloudflare.

I feel like I'm missing something simple here, but can't quite find it. Where should I look?

Thanks,

Upon further testing, this issue appears isolated to my instance of the Arc browser (Chromium) and has yet to fail in Firefox. I believe this to be a browser bug/issue more so than an Linkding/Cloudflare Tunnel issue.
