bug: IPv6 addressing doesn't work

[ghost]

Describe the bug
The application doesn't seem to support IPv6 addresses in the format: https://[fe80::1ff:fe23:4567:890a]/navidrome (address taken from the Wikipedia IPv6 article only to demonstrate the format)

I tried logging it as the admin user/as a non-admin user - nothing. Tried a simpler password - no dice.

Nginx access log shows no requests made from the device.

To Reproduce
Should be clear from above.

Expected behavior
Same behavior as with IPv4/DNS.

Smartphone (please complete the following information):

• Device: Xiaomi Redmi 9T
• OS: Android 11 (MIUI 12.5.8)
• Subtracks version 1.3.0 (from F-Droid)

Edit: Worth noting that I'm also using a self-signed cert. Possible duplicate of #84? If so, please close.

Has your self-signed certificate also been signed by a CA that is trusted by your phone? In that case it should work without issue, but if not then that would be an issue. I would be curious to know if your issue persists with the v2 alpha though, if you want to try it you can get that here: https://github.com/austinried/subtracks/releases/tag/v2.0.0-alpha.1

Hey @austinried thanks for the reply. I tried again with v2.0.0-alpha.2 and it didn't work. I can confirm that I have a trusted self-signed CA installed on my Android phone and that the server is signed by that CA (and a standard lock icon is shown by Chrome without any warnings, hence the cert is trusted by the phone).

The bummer is that no error messages appear inside the app. And sadly there were also no new logs in nginx access logs.

PS. In case someone's interested, this is what I used for generating my certs: https://gist.github.com/stacksmash76/d8076a49da4ca17e460f1c9c5c1f8b7c

Gotcha, thanks for the update. I think with the alpha it might have to do with the way I'm trying to parse that into a URL, so I'll have to look into that. More/more specific error messaging is something I'm also going to get in before the beta to hopefully improve that experience as well.

How about alpha 3? There should be an error message of some kind this time, and you can share your logs at the bottom in settings for more info.

Yep, indeed, there's an error now.

HandshakeException: Handshake error in client (OS Error: CERTIFICATE_VERIFY_FAILED: self signed certificate(handshake.cc:393))

Confirmed again in Chrome, certificate is shown as valid and "verified" by Chrome. Going to "Encryption & credentials -> Trusted credentials" I see my CA cert under "User", which, again, seems fine.

Maybe there's some flag which isn't enabled correctly for the underlying Android implementation to handle self-signed certs (even though they're signed by a self-signed CA)?

Yep, looks like I forgot a bit of network security config that would allow this. By default the app was only trusting the system CA store, and not the user CA store, so I've added that into the config.

If you want to try the build from this PR I think it should get you past that error at least: https://github.com/austinried/subtracks/actions/runs/5008207271?pr=180

Unfortunately, same error message. Cleared app cache, uninstalled and then installed the apk artifact.
