Mautic Segments

Hi I have searched the forum and of the two threads nothing really helps.
I have gone into Mautic settings and enabled HTTP basic auth & API enabled. These are done sucessfully as the API setting tab now shows in the configuratiion.

I then installed the plugin and after entering my Mautic installation I can not find any segments (I set one up as Opt-in its live and has a globe)

I can use (example) http://yourdomain/mail/s or any further config to not get an error but it still will not find any lists. Please help
