HP Data Protector 9.9 Not working, after changing domain name

Dear Sir.

Good Day.

we faced unexpected issue with DATA Protector Cell Manager after we change our domain name with a new domain.

error is , Failed to connect SERVER port 7116 Connection refused.

just we change domain from sss.org to mmm.org  ( just for example ).

i tried to re-generate new Certificate but problem still exist. 

is there any solution for that issue ?
