If I go to the Kodi connect website it is secure. However the IP address https://46.101.194.37/ the app is using to connect is showing as unsecure from chrome browser for some reason

Because certificate is always issued to domain, no to IP address.
Kodi connect addon is actually using a normal hostname to connect to the server, which gets translated to IP address.
But certificate validation should happen against the hostname.
As I said before, there is something wrong with the underlying implementation of network library, which causes this to fail.
