[Question] Airsonic-Refix compatibility?

[GioF71]

Hello, I am trying to run Airsonic-refix on LMS, but I get an error saying "Could not log in. (Failed to fetch)". Authentication isn't actually the problem, but something fails after that. I already have opened an issue here. Do you have an idea of what could be happening? I already enabled debug logging but no new information appeared (at least, that I could notice!). Thank you for any help!

Hello Well if LMS does not log any further operation, I guess the ping response is somewhat badly parsed or not accepted by airsonic-refix. Maybe there is a field or a version in the response that triggers this error?

Hello, I just checked lms vs navidrome for the authentication request, and they are very similar. I noticed that the app sends "1.15.0" as the "v" field, but both navidrome and lms respond with their subsonic api version. So right now I have no idea of what is going on...

{
    "subsonic-response": {
        "openSubsonic": true,
        "serverVersion": "6",
        "status": "ok",
        "type": "lms",
        "version": "1.16.0"
    }
}

{
    "subsonic-response": {
        "status": "ok",
        "version": "1.16.1",
        "type": "navidrome",
        "serverVersion": "0.52.5 (c5560888)",
        "openSubsonic": true
    }
}

Hello, from further tests it seems that the password is sent as-is and not in the enc:xxxx form.

[GioF71]

I believe lms does not support clear-text passwords without hex encoding, am I right? Otherwise the login attempt should go through...

[epoupon]

I can't test right now but according to the code it should be supported. Do you have details on lms side when enabling debug logs? You should see auth failure/success

[GioF71]

I will try again and report... do I need to enable debug for this? Thank you

[GioF71]

Doesn't seem to fail after the first attempt where the logs says "'Token authentication not supported for LDAP users." The next attempt is done with clear-text password, and it seems to me a http code 200 is returned, am I wrong? Thank you for any help!

Are you sure you enabled the debug level for the logs?

[GioF71]

I tried before without -debug in log-config in lms.conf and found no additional information as far as I understand. Anyway I tried again just now, here is the log without -debug:

Actually I changed the log config a while ago, you just have to put the min severity you want, see: https://github.com/epoupon/lms/blob/a7f4672d65bc48e2e7c943446b46e45e9a1782dc/conf/lms.conf#L14

You need to put log-min-severity = "debug";

[GioF71]

Ok! So this is the output with the new log settings:

Hello, I just checked lms vs navidrome for the authentication request, and they are very similar. I noticed that the app sends "1.15.0" as the "v" field, but both navidrome and lms respond with their subsonic api version. So right now I have no idea of what is going on...

{
    "subsonic-response": {
        "openSubsonic": true,
        "serverVersion": "6",
        "status": "ok",
        "type": "lms",
        "version": "1.16.0"
    }
}

{
    "subsonic-response": {
        "status": "ok",
        "version": "1.16.1",
        "type": "navidrome",
        "serverVersion": "0.52.5 (c5560888)",
        "openSubsonic": true
    }
}

Well if LMS returns this message, even for clear text passwords, I really think the problem is on the client side.

[GioF71]

Hello, actually I could not make a request with clear-text password, because I had to escape some characters. But I will try!

[GioF71]

I just tried with cleartext password using postman... and it works. Let's see if there is some feedback from the airsonic-refix side. Thank you for your support!

[GioF71]

Hello, I tried again today. I configured a reverse proxy for Airsonic-Refix, while I already had traefik set for lms. So now it seems to me it's a CORS issue. Are there settings available on lms, or is this something I should probably change on the client side? Thank you!

[epoupon]

Hello! The internal web server (wt-httpd, used by lms) states that cross-origin requests are always disallowed. Maybe you can hack with the proxy and add the relevant Access-Control-Allow-Origin headers, but I have not tried myself

[GioF71]

Thank you. I cannot seems to be able to configure traefik correctly. The think that puzzles me is that upmpcli with its pysonic library connects without any issue, even using the reverse proxy on top of lms. Instead with airsonic-refix I keep getting the same issue mentioned here.

[GioF71]

I sorted it out, I was applying the traefik configuration to airsonic-refix instead of to lms. Silly!

[epoupon]

If it works now, then it is a good news!
