Chrome 58 breaks HTTPS Inspection

Today (April 20 2017) we discovered this when Chrome auto-updated a few of our PCs.

The link below is from the forum for Sophos Web Appliance, for which a patch has apparently been released.  

The problem description is exactly what we have been seeing today with UTM.

Until Sophos has a patch available for UTM, the necessary workaround is to switch all Filter Policy definitions from HTTPS Decrypt-and-Scan to URL Filtering Only.
