Apologies if I missed this in - errata - entirely possible
After upgrade to 1.4.7 seeing this error when attempting to access control panel...
does use panel redirect plugin - and using default 8443 port - was working previously
going direct to https://panel.domain.com:8443 works fine - So not urgent
The proxy server could not handle the request GET /.
Reason: Error during SSL Handshake with remote server
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
This only shows up on one server - older one - so I'm sure its something I did vs I-MSCP...
but redirect doesn't work on my new one anyway
