Why do I receive the following Event log message: "SSL Proxy failed while processing CLIENT HELLO"

Products

• ProxySG Software - SGOS

Issue/Introduction

The following error is registered when there is an invalid SSL certificate:
  "SSL Proxy failed while processing CLIENT HELLO"

This error occurs when: 

• The ProxySG blocks all HTTPS traffic that does not have a valid SSL certificate (Secure Sockets Layer certificate).
• This affects any port 443 traffic that does not use SSL certificates (such as some peer-to-peer, IM applications, legacy applications).
