Since quite a while I only get an empty playlist and the login to Naughtyamerica.com does also not work anymore when trying to load  https://api.naughtyapi.com/heresphere

Now I found out that this seems to be a general problem since other users reported the same problem. Any fix for this? 

The issue is on NAVR's side. Their anti-bot security system is blocking requests made by HereSphere. They said they're working on it, but I don't know if or when it'll be fixed. You can try letting their support team know that the issue is important to you so they prioritize it.

Thanks for the info and your effort!

Looks like NA has fixed the issue, and the HS web API should be working again with their site.

Unfortunately the issue is still the same on my side. Nothing is loading and login is not possible. :(

Thanks for the update though.
