"Invalid private key" message after upgrading NC

NC has been upgraded to 25.0.1.
Now, after beeing logged in, i get the error message as of subject.
When doing “occ encryption:status” i get

  - enabled: false
  - defaultModule: OC_DEFAULT_MODULE

Something wrong?

Don’t know how to resolve.

I am also seeing this, but in the dashboard

There was some hope this to disapear with the upgrade to “”. But nope, still remaining.

Disabling “Default encryption module” did it in my case
