HA keeps restarting every 5-10 minutes

with install-media i did mean, another sd / SSD , or same ?

Oh, yes, another SSD as my NUC as integrated SSD (might be nvme)

Ok, when people says Reboot, it means Reboot, i.e turn off your server AND start it again ā€¦ did you just Restart ?

No Reboot inbetween ! , To rebuild the DB a Reboot is needed

So here it 's Supervisor which are ā€œRestartingā€ ā€¦ NOTE the gap of 5min, of itā€™s repeated API requests

And among other things complaining about ā€œmissingā€ schemas

Also itā€™s fetching Updates from GitHub,(meaning so far so good), just before these ā€œmissing schemasā€ occurs

Im not aware whether itā€™s do to the fact you might have installed ā€œlatestā€ HA-OS , and ā€œappliedā€ and ā€œolder/already corruptā€ backup-file , or whether HA can/will recreate the DB after a Reboot

Othervice as you See, NodeRed SambaShare

I guess Iā€™ll be rebuilding from scratch. Just reinstalled and no reboot for now

First, save your yaml files. They wonā€™t change much, if at all.

Weird issue. I completely reinstalled, used to work great, didnā€™t add anything special, just add-ons.

All of a sudden, it seems like itā€™s crashing every day (instead of every 7 min)

Well, as your on whole new hardware, with ssd instead of sd, and a new ā€œclean installā€ ) NO ā€œoldā€ broken/faulty backup files applied ?, then i guess you have to monitor, your log-files ( and your storage-size ) , AND btw ( it seems like itā€™s crashing every day ) is Absolute not a ā€œtechnicalā€ description, itā€™s in fact just useless information , and you dont even specify what crashes ???, Supervisor ??? Host ??? your NUC ?
What does the logfiles says ??? have you tried enabling DEBUG ???.
Obviously beside your ā€œreporting methodā€ you should also ā€œexamineā€ your install/maintenance/troubleshooting Methods
