Unable to get Sonarr running on my raspberry pi 3 running OSMC

I’ve tried every single guide out there trying to get Sonarr running on my pi but i cannot get it right.
This time i’ve managed to get everything right but i cant get Sonarr to work, Whenever i try access its web UI it fails.

Can you guys guide me to the right direction ?

have you tried getting support form the Sonar developers ? instead of trying random guides.
