Memberships 2 pro comms conflict

When we have the memberships 2 pro plugin active we are getting a comms error. net::ERR_NAME_NOT_RESOLVED

This only happens when we have this plugin active. We performed a plugin conflict test. We turned off all plugins and turned them on one by one. We had all plugins on with no errors. Memberships 2 pro was the last to activate before getting to the error. This error only fires when logged-in.

I have support access open if you need it.
