HPM warning - Unable to refresh null

[fritz]

Receiving an "unable to Refresh null" from HPM after updating apps on hub after updating C-7 hub firmware to 2.4.0.151.

All HPM installed apps appear to be up-to-date and working correctly. No unmatched apps.

Any ideas what the problem is and how to correct?

Thanks

Getting something similarly weird here on 2 of my 3 hubs:

Working fine on the 3rd hub. Tagging @csteele

"Unknown Host Exception" -- indicates there's no such place as raw.githubusercontent.com

That's clearly impossible, so there's two possible reasons.. 1) github made a typo while modifying their DNS system. Not really likely since "working fine on 3rd hub" 2) the hub does not have DNS working properly. This is the most likely. Go to Settings: Network Setup: Network Test (at the top) and then Ping somewhere by name. If you get results, DNS is working, if not, fix DNS on your hub.

Above is what working looks like..

That did it - somehow, two of my hubs simultaneously forgot they had static IP addresses. Weird. Thanks!

My issue was NOT the same as @jwjr. My issue was caused by Watchtower code repository being moved from HPM when app upgrade from v2 to v3.

Here is the solution:

[RELEASE] Watchtower long-term metrics app

Released version 3.2.1 with the following small fix: Fixed Don't show leave confirmation on embedded dashboards - @amithalp If HPM does not offer this version for update, first un-match the "Watchtower" package (from HPM Settings page), then run "Match-Up" to link it again, and finally check for updates again. Have fun!
