Google maps api and https

I am using the google maps API with regular key (not premier). When connecting to my server with http, everything works fine, but when connecting with https i receive the following instead of map:

initialization failed please check the API key swf location, version and network availability

Is that because it is not p开发者_如何学运维remier key? can I force the google maps API to use http instead of https so that I will receive the maps?

Https in the Google Maps API is no longer restricted to Premier users. It is now available to everyone.

https is only supported for premier maps api customers.
