To manage this problem, we can ask vCSA to regenerat SSL certificate to meet with new IP or hostname. Login to vCSA admin page (eg : https://vcenter-lab.excellent.co.id:5480) then select the Admin menu and select the option Enabled Certificate Regeneration. Once completed, go to the System menu tab and select reboot vCenter .
