Your server’s SSL certificate is incorrect or you are using wrong value for Domain field (maybe IP?). You should either login with correct value or you can go to Advanced menu and disable Certificate hostname verification. You also would need to accept Self-signed certificates in the same menu if you use SSL certificates generated by Openfire.
