Connection to navidrome fails

[Pierric82]

Hi,
I'm trying to connect mopidy to my Navidrome library through this plugin. I know Navidrome's API works as I'm using it through a few android apps using the subsonic API. When I try to connect from mopidy, the front-ends show subsonic but the artists, albums and directories views are empty. The logs show connection errors:

The config section for subidy is simply as follows:

[subidy]
enabled = true
url=https://[edited]
username=pierric
password=[edited]
legacy_auth = false
api_version = 1.14.0

I've tried legacy_auth=true, and api_version=1.16.1, but to no avail. Am I missing something in how subidy is supposed to be used? How can I further debug?

Thanks in advance!

Some additional insights:

• this seems to be linked to the call to the API failing when performed via libsonic
• I can access the navidrome API from the same machine without problem either by using curl on the CLI or by opening the python interpreter, importing libsonic and connecting to navidrome with the same parameters subidy is doing
• but from within mopidy-subidy, I get an SSL error if I try to access the navidrome server directly with http (so, there should be no ssl at all!)
• and also from within mopidy-subidy, I get a 403 Forbidden if I try to access navidrome via my public URL, which takes me to cloudflare with a cloudflare certificate, and then to my server (there is another certificate on my server but I don't think this matters). Again, strangely, when reproducing the same call to libsonic from the python interpreter, I have no errors and can retrieve API content like artist list etc.

(To confirm those findings I've located the subsonic-api.py file and added extra logging there)

EDIT: the 403 is resolved by disabling browser integrity check on cloudflare. Probably not a good idea though? But thanks to this I DO see the contents of my navidrome library! I would prefer to access locally via HTTP however.
