Say you want to log in to Bentley's website, so you go to https://connect.bentley.com. You enter your email address and password and then hit the Sign In button. You would expect to be logged in wouldn't you. But, not necessarily if you are connecting from a corporate environment (and let's face it, most of Bentley's customers will be). Instead you may well get the error Secure Connection Failed:
And why is that? Well, for some totally unfathomable reason someone at Bentley has decided that this page should use TCP port 8443, instead of the standard port of 443 for HTTPS traffic. And of course most enterprises restrict outbound connections to standard ports for security reasons.
So why has Bentley done this? Who knows. But whatever the reason, it's Not Good Enough.
