I'm setting up NMC but it doesn't work. I can't get it pass this error message:

"Those changes have been applied, but the NMC connection was NOT successful. Your computer may not be protected. It is recommended that you fix these issues immediately.

ERROR: NMC http://xx.xx.xx.xx:80 found, but security information is incorrect. Check the Authentication Phrase and User Name."

There was already a passphrase in the field (which I can't see of course) and I don't remember setting one.

I also tried what I found was the default passphrase "admin user phrase".

What can I do?

Thank you
