KeePass OTP generierung klappt nicht mehr

I have also changed the secret. And I pasted the new secret on recovery. Maybe this is the problem?

I see. You need exactly the same HOTP secret you have generated back then and saved on the slot. Unfortunately, if you have not done any backups of the HOTP secret string or firmware export before overwriting the HOTP slot on the device, you might have lost the chance to recover the database.
