Issue/Introduction

ProxySG generates error when notify page should be showed to the end user:

 

<Error>

<Code>NoSuchKey</Code>

<Message>The specified key does not exist.</Message>

</Error>

 

Environment

Virtual notify URL is configured with default URL: "http://notify.bluecoat.com/".

The issue can be observed on specific browsers such as Edge and Chrome and not observed with Firefox depending on browser settings.

Cause

HTTPs is a default protocol for Сhrome and Edge browsers. When Virtual notify URL is configured with HTTP protocol and automatic switching of protocols from HTTP to HTTPs is enabled, browser will access notify page over HTTPs.

As a result connection to "https://notify.bluecoat.com" is now using TLS and has to be SSL Intercepted by Proxy.

Resolution

Modify protocols from http to https under Virtual notify URL: "https://notify.bluecoat.com/". Alternatively, disable automatic protocol switching from HTTP to HTTPs on your browser.

Verify if notify.bluecoat.com is SSL Intercepted.
