Communication Error: (35) Unknown SSL protocol error in connection to webservername:433 (error 35)

I have a two-machine deployment and the SSL certficate was generated from Comodo as a SHA-256 (which FileMaker supports). One of my users setup a Custom PHP site and whenever someone tries to login, it comes up with this error. Communication Error: (35) Unknown SSL protocol error in connection to [webservername]:433 (error 35).

 

Web Server details

Windows 2008 R2 SP1

IIS 7.5

FileMaker Server 13.0v5

 

All latest Windows updates have been installed. (Rebooting the server did not resolve this issue nor restarting IIS, nor restarting FileMaker Server, nor restarting the Web Publishing Engine). Users were able to login before the v5 upgrade, so I'm not sure if that has any bearing?
