OTC Authenricator and Recovery Codes auth fails on active instance

Is your n8n volume has been changed?

I’m not sure, how it can be changed - if the system properly working and actively serving API requests and all the nodes are working properly.

Or the encryption key has been entered incorrectly?

What I have to say - the section N8N_ENCRYPTION_KEY={{mysecret}}
I created manually after I was denied accessing the dashboard and found this (following next log):

  1. 1st line whowing there is encryption key found
  2. last two lines - just the same denied reties with OTC Autneticator

The only issue — is Authentication.
As you may see - nodes acting properly.
And my email:pass is also valid.

But when I tried access with OTC it says - neah…
