Cannot expose two endpoints for one WCF service - wcf

Question

I'm trying to set up a WCF service with two endpoints which both expose the same service contract as follows
What I want to be exposed to clients...
http://server:1955/myService/secondEndpoint and
https://server:443/myService/
The issue appears to be with multiple base addresses.
If I explicitly specify the full address in each endpoint and omit the baseAddress section I get the following error
"When 'system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' is set to true in configuration, the endpoints are required to specify a relative address. If you are specifying a relative listen URI on the endpoint, then the address can be absolute. To fix this problem, specify a relative uri for endpoint 'http://server:1955/myService/secondEndpoint'."
I therefore put relative address in the endpoint and add a base address
Could not find a base address that matches scheme https for the endpoint with binding WSHttpBinding. Registered base address schemes are [http].
I feel like I am going in circles with this. Any help much appreciated.
