Errors at SSL-Inspection.

Hi BeEf,

Thank you for reaching out to Sophos Community.

19018 - The connection was dropped/rejected by the client application during the handshake. See the 'Message' field for more information. (This message is most commonly seen when the client application rejects the re-signed TLS certificate. You may see TLS handshake fatal alert: unknown CA(48) or TLS handshake fatal alert: certificate unknown(46), or possibly other TLS alerts. The alert code is sent by the client, and is defined in the TLS protocol standards. The exact response depends on how the client software was written.)

Hello   LuCar Toni

this references a very old post. Can this be transferred to an official piece of information?
