http vs https with relay response URL and receipt URL

[mschloss]

I just got a new certificate that is SHA256 and I'm getting that dreaded error "An error occurred while trying to report this transaction to the merchant."

When my relay response and receipt URLs are non SSL (http) everything works fine, but when the URLs use SSL, I get the error in sandbox and production servers.

I thought this issue was fixed from reading other threads - but is that because everyone is just not using SSL for those pages?  I know it's still secure but I'd like to be able to use SSL.  What should I try? I'm using the DPM method.

Hello @mschloss ,

Are you able to provide more details about the error returned during the SSL handshake?  You might also want to test your site's certificate and configuration using https://www.ssllabs.com/.
