• The following entries may be observed in esxupdate.log on the affected ESXi host:

var/run/log/esxupdate.log

Host cannot download files from VMware vSphere Update Manager patch store. Check the network connectivity and firewall setup, and check esxupdate logs for details.
[Errno 4] IOError: <urlopen error [Errno -3] Temporary failure in name resolution>'

 

Environment

VMware vSphere 6.x , 7.x , 8.x

Cause

ESXi host is unable to communicate with VMware Update Manager running on vCenter Server through port 9084, 80, 443.

Resolution

Port 9084, 443 and 80 are required for VMware Update Manager. Validate the below details and if any issues found refer the related document

1. Ensure the Ports 9084, 443 and 80 is open from ESXi to Update Manager Server or vCenter Server, check TCP and UDP ports required to access VMware vSphere Update Manager for more details
2. Test connection for each of the ports, from ESXi putty session run the below commands to the VC
   • nc -z [VCSA_IP] 9084
Expected response: Connection to VCSA_IP 9084 port [tcp/*] succeeded!
   • nc -z [VCSA_IP] 443
Expected response: Connection to VCSA_IP 443 port [tcp/*] succeeded!
   • nc -z [VCSA_IP] 80
Expected response: Connection to VCSA_IP 80 port [tcp/*] succeeded!
3. If the above commands are not succeeded, please check the 9084, 443 and 80 port are reachable get these ports open between ESXi and vCenter/VUM.

Note: Make sure both vCenter Server and ESXi hosts have proper DNS entries and the forward lookup and reverse lookup for vCenter Server is working from the ESXi as expected using the nslookup command
