Description (partial)

Customer is receiving log in prompts while browsing to websites. The customer's LDAP and AD connectivity is working correctly, and there are no observable issues in the connector.log file.

After upgrading to,  when a client sends a http request through the bypass proxy, this proxy will reply to client with Authentication request.  The client receives this authentication request and sends new http request but this time with Proxy-Authentication header and NTLM token inside.

The Connector is cutting off the Proxy-Authentication header and bypass proxy doesn't receive authentication data from the client and sends an authentication request.
