Pushover gone! After automatic migration from YAML config

Today I upgraded to latest 2022.9 version. I got a warning that Pushover is no longer configured via YAML but as integration.

But Pushover is not migrated?? I cannot see it under integrations. And if I want to add is as new integration it fails.

Errors in log file that messages cannot be send.

So I guess somewhere in an hidden setup file there is some leftover over the migration that failed.
Where are the settings stored?

Anybody else the same problems?

There was a multi-target bug that was fixed in x.9.2 I believe.

Thank you.
I updated to 2022.9.4.

Still not able to add pushover as new integration.

Did you by any chance have multiple pushover accounts setup?

No. I am using one pushover account.

Is it possible that there are some settings left on the server.

Can I manually remove them?

If you haven’t already, I would remove everything related to Pushover, and then re-install after a reboot.

I cannot. The integration doesn’t show up. And I cannot reinstall it. So I am stuck without Pushover.
