Rebooted host, same deal…, ideas ?

2

The 5th host reboot was the charm…, no idea what the issue is

3

Same again, cannot update the supervisor…what the hell ?

4

It says its unhealthy. When you go to the supervisor panel you should see a “system is unhealthy” warning. What does it say when you click the link for more info?

5

It says nothing useful, random errors for the OS not running properly and some missing components. This is running on HA OS, so that’s not possible. Just have to hard reboot one or more times to get it going again. This now happens every time I try an do something using the supervisor

Same issue here too. I have multiple HA with 32/64 bits on ARM. That doesn’t change anything.
Post “http://supervisor/snapshots/new/full”: context deadline exceeded (Client.Timeout exceeded while awaiting headers)
I believe the problem may come from the SSH & Web Terminal addon (8.2.1 / Unprotected mode):

21-05-16 08:09:18 INFO (MainThread) [supervisor.addons.addon] Building snapshot for add-on a0d7b954_ssh
21-05-16 08:11:09 INFO (MainThread) [supervisor.addons.addon] Finish snapshot for addon a0d7b954_ssh

The command ha snapshots new --name “Test” is launched from the exact same addon so it is not an coincidence. I guess the client HA snapshots has its communication broken when the full snapshot server process executes the SSH addon where is belongs.
Now I use the supervisor API to trigger the snapshot:
curl -sSL -H "Authorization: Bearer API_CODE" -d '{"name": "Full Snapshot"}' -X POST https://fqdn_url.example.com/snapshots/new/full
the fqdn_url can be a new proxy from Nginx Proxy Manager or any other RP.
The destination URL: http://supervisor:80
and in advanced tab, you need to add:
proxy_read_timeout 14400s;
the number of seconds will be the max time needed for the backup.
