Hmm... In the logs I can see that it can successfully hit the host because you are getting HTTP status code 401.

[package:lunasea/logic/clients/nzbget/api.dart] [getStatus] [NZBGet: <POST> HTTP Status Code (401)] [Exception: null]

Status 401 means unauthorized, are you 100% sure that the username and password are correct? On that, do the username or password contain any special characters, such as symbols like @, !, #, etc.?

I was experiencing problems myself when using passwords with symbols, but I also was not able to login on the web GUI so I assumed it was a problem with NZBGet.

This is what I get when NZBGet's authentication is disabled

It still seems to be returning 401 Unauthorized continually. Do you have any authentication layer on top of NZBGet, maybe through NGINX or Apache?

[theg00s3]

I do have an authentication layer with nginx, so my url is username:password@website.com, which works for Sonarr, Radarr and Lidarr

[JagandeepBrar]

I think this problem may be out of my control, because I already tried preventing this by passing the username and password to NZBGet by setting the "authorization" header in base64 in the request, seen here:

https://github.com/JagandeepBrar/LunaSea/blob/73eaa245284b33b2509228f7dd84b1c6291521e7/lib/logic/clients/nzbget/api.dart#L23-L27

If you look at the NZBGet API, they also support passing username and password in that same format (username:password@host), and I feel like these must be interfering with each other. I can't think of any other reason that it seems to be failing authentication if you are confident that the username and password combo are correct.

Can you see if it works if you disable the NGINX authentication layer?

[theg00s3]

Disabling nginx's basic auth works, but strangely I didn't need a workaround when using NZBUnity which unfortunately doesn't release its source code.

[theg00s3]

I got it working. Instead of putting the nginx credentials in the url, I put them into the username and password box in LunaSea.

So my URL is website.com and then the nginx credentials are in the nzbget credential boxes.
