verbose, the error message shown on a blank browser window is:
cURL error 51: SSL: certificate subject name 'my.domain.name' does not match target host name 'internal.ipaddress.of.server'
This happens when I call my server via its private IP address.
When I call my server via its public url, I get the following error:
cURL error 51: SSL: no alternative certificate subject name matches target host name 'localhost'
I applied the necessary upgrade patches, checked my SSL setup with www.ssllabs.com routines (and came up with an A+)
I am at a loss - and have to admit that I am not very knowledgeable in terms of SSL.
