Certificate not valide after IP change

Hello everybody,

I hope some of you are enjoying their hollyday and for the other, good luck !!!

I have a little issue with my openfire server (3.5.2) since I have made an IP change of it :

Server Certificates -> Found RSA certificate that is not valid for the server domain.

In the Host (alias) I have to line ( *.10.9.1.1 (10.9.1.1_dsa) and *.10.9.1.1 (10.9.1.1_rsa)) and 10.9.1.1 is the old IP of the server.

I think I have to generate new self signed certificate in order to remove this warning and to remove the Found RSA certificate that is not valid for the server domain. in the first page.

All my client are using Pandion and are using secure connection (security connection mandatory in my openfire configuration).

Is someone could help me in order to solve this issue ?

Thanks !!!
