HA Operating System Update Failure

Hello - First time using HA - Had a HA Blue system in the box I finally got around to install today. Updates worked except for the HA Operating System – the installed version is 5.13, trying to update to 9.5 – I get an error “Failed to call service update/install…”

I checked my system and it is noted as stable - no errors. I haven’t done much except turn it on so no customizations.

Do I need to install an interim version or is it something else?

This post could help you to find the solution…

Thanks - strange, I am able to update core, add add-ons no issue. When I go into ssh and try it that way using ‘HA OS UPDATE’ – I get an error “ERRO [0000] Unexpected Server Response. Status Code: 500”

OK - so I rebooted the system 3 times in a row and I got it to finally work. Strange but moving forward! Thanks
