13.0U6.2 upgrade check fails

For a few days now, an upgrade check for 13.0u62 gives an error message of “Unable to connect to url https://update-master.ixsystems.com/TrueNAS/trains.txt: Automatic update check failed. Please check system network settings.”

Not a network issue - I can see the dir fine.
