Fetch data from API issue

Fetch data from API issue

Hi,
I want to get data with call API from Mailerlite in Analytics Plus, but show me error:

Error while reading the URL contents. Please verify whether the server (host machine) containing the URL is connectable.

I checked URL in browser and attached screenshot. What should I do to resolve this issue?

Analytics Plus v4700

Thanks for helping
