Website Block Message for valid blocked HTTPS sites

 

Hello,

I've got a client running Sophos Enterprise Console and recently enabled Web Control so they could move away from a web proxy provider and save money.

*Enterprise Console version 5.5.0

*Client Agent (Endpoint Security and Control) version 10.7

This works fine for all the sophostest.com sites and everyone is happy with the solution - however any BLOCKED sites that are accessed on HTTPS just result in:

 

"This site can't provide a secure connection

<website> sent an invalid response

ERR_SSL_PROTOCOL_ERROR"

 

 

Non-blocked HTTPS sites work fine.

Could anyone advise a way to resolve this please as I'm keen to provide users with a more meaningful message to reduce support calls.

 

Kind Regards,

Mike
