the collector running on internal/private server , cisco nfc license tied public ip , hence hostname set public ip in /etc/hosts file

the sec admin has allowed ports 22 , 1099 yet above exception thrown. need change configuration in server or in firewall?

this issue resolved using new license cisco generated using private ip. vishawanath , ejp help.
