Hello Anish,
There is not much to go on here with your question, but perhaps this will help:
How do I configure the Subject Alternative Name (SAN) Certificates in WebSphere Application Server?https://www.ibm.com/support/pages/node/1168858
Just put the correct values in the SAN and those hosts would be allowed to connect.
Regards,
Bill Holtzhauser
