Henrik Thanks for this. I looked further and worked out how to allow the CONNECT method for a particular host without authentication. I had not realized this option was available. I was wondering whether I can determine why the authentication from WSUS is not working and whether there is anything that can be done about it rather than having to allow access via CONNECT without auth for the WSUS server?

Looks like your config still requires authentication for the CONNECT method. Regards Henrik
