Unable to start NUT addon: around password

Third party integrations
1

Hello,
please help me with an issue:
Network UPS Tools (NUT) addon doesn’t want to start - it demands a password (please find the log below).

But it is impossible to set the password - error appears: Unknown error, see supervisor logs.
The HA log contains:
Failed to to call /addons/a0d7b954_nut/options/validate.

How to fix this problem and start NUT addon?

You don’t have a password.

When I set password and try to save configuration error appears:

Failed to to call /addons/a0d7b954_nut/stats - Container addon_a0d7b954_nut is not running

so looks like closed circle - to start addon needs password, to set password addon needs to be started )))

NB: configuration can be saved without password only

Good afternoon, was a solution found? I had the same problem again.

I figured out the error “Can’t fetch HIBP data: Timeout” when entering my password. The problem was related to an unanswered request to the HIBP service (api.pwnedpasswords.com). I solved the problem by temporarily disabling the password checker and then re-enabling it.
