Unable to connect Emby to Soundiiz.

[jdewoody71 9]

As requested, I've created a new post.

I get invalid credentials if I use my Emby connect email or my username, yet I can log into Emby with either in a new tab. I've even tried my wife's account. I can also access Emby in a browser or on my phone outside my home. I've also tried using my public IP & port with no luck. I checked Emby logs and I don't see anything but I'm pretty sure it's is because the app never connects successfully. The support at Soundiiz doesn't seem to know how to support their own product, they sent me this for troubleshooting:

If I was a dev, it might be different. Can you folks think of anything I could try? Thanks!

Hi, I'm assuming the login error is coming from our emby connect server when you try and sign in with that username and password. That's why you don't see the activity in your server log.

Does Soundiiz have any logging that could help and see what's going on?

Hey, same problem here. On the soundiiz connect webinterface I get the error: "Valid credentials but invalid server configuration."
I tried each combination with public ip, domain, and ports 443, 8096 & 8920.
The emby server is also reachable from everywhere. It is worth to mention I run the emby server behind nginx proxy manager. @jdewoody71 are you running behind a reverse proxy too?
Unfortunately I couldn't gather any more info on soundiiz

Can you ask them what this message means?

No proxy server here.

I ended up giving up on this. Emby sorely lacks regarding playlists, they could take some lessons from Plex in that area. I set up a Navidrome dock server in unRAID at home and use Symfonium for my phone. It's not 100% perfect, but I have zero issues managing all aspects of my playlists.
