I have an intermittent issue with both users using the Microsoft Office repair utility on Windows and doing Windows updates when they're on a connection behind a Sophos XG firewall.
With windows updates, the devices are stuck on "downloading - 0%"
The repair utility returns an "Online Repairs need the internet and it looks like you may not be connected", and does almost immediately upon being run.
The computers are connected to the internet and can otherwise access all websites, including the various MS websites.
It's not a a PMTUD issue (my usual go to when this sort of weirdness happens). If the device is tethered instead to a 4G connection or otherwise bypasses the Sophos XG, the issue goes away.
The device has the Office365 web exceptions setup as per https://community.sophos.com/kb/en-us/132291
Sophos is an XG330 running 17.5.1 MR-1 and there is nothing immediately obvious in the system logs.
