My service works perfectly in Sandbox, but when attempting to access it in prod, it always throws
<Errors> <Error> <errorCode>UNSUPPORTED_CLIENT</errorCode> <message>HTTPS Required</message> </Error> </Errors>
This error happens even when accessing the service via HTTPs.
Here is my functional sandbox one https://fpitesters.testbed.cs7.force.com/webServices/services/apexrest/respondentPortal/
You will get an auth token error there, that is expected. It's just a basic security measure.
And here is the production one https://fpitesters.force.com/webServices/services/apexrest/respondentPortal/
UPDATE: So as Josh Birk pointed out, you do need to use the secure sub domain. If you try to just use HTTPs on the regular URL you do get redirected to a regular http domain. So with that in mind, the url for my service should be
However that URL says that the service couldn't be found.
<Errors> <Error> <errorCode>NOT_FOUND</errorCode> <message>Could not find a match for URL /respondentPortal/</message> </Error> </Errors>
Not really sure where to go from here. Is this a bug?
