Environment

VMware Live Site Recovery 9.0

Cause

Name resolution for vCenter during registration of VLSR taking longer time (more than 10-15 seconds) resulting in the socket timeout error.

(in /var/log/vmware/dr/drconfig.log)

Resolution

• Involve Administrators managing DNS / Domain Controller to investigate delay in resolving forward/reverse addresses (of vCenter and VLSR).
  
  
• Once fixed, re-register VLSR from Appliance Management UI.
