Problem after cross certifying 2 server/certifier

Hello,I follow the procedure to cross certiy 2 server but I decided to cross certify the certifier instead of the server. Now I got an error message stating:

“server error:Your public key was not found in the name and Address book”.

It is surprising because a new “Notes Cross Certificate” document was created in the names.nsf with a public key code that I can see while I edith the document.

What does I missed?
