Setting up spotify playlists

Configuration Frontend
1

Can any help show me what i m doing wrong?

Trying to link my spotify playlists got as far as authorisation.

but when i click the link to verify i get:

INVALID_CLIENT: Invalid redirect URI

Now i know this has to do with re directing link thats added to the developer app in the set up

when i click the link to verify this is what it reads in the address bar:

https://accounts.spotify.com/authorize?client_id=3197ac260de14fe7849823ef6bdbd561&response_type=code&redirect_uri=http%3A%2F%2F192.168.104.204%3A8123%2Fapi%2Fspotify&scope=playlist-read-private+user-modify-playback-state+user-read-playback-state+user-read-private

which suggests its looking for http://myip:8123/api/spotify i have tried this but to no affect
i have previously linked spotify for a media play successfully already.

can anyone point me in the right direction?

Thanks
