ESXi host is unable to communicate with Update Manager through port 9084.
The port 9084 is required for VMware Update Manager.To resolve the issue make sure from ESXi to Update Manager Server or vCenter Server Port 9084 is open. Also check Update Manager port requirementsUpdate Manager Server is installed on a different node from the vCenter Server 6.x Example: To test the connectivity between ESXi and vCenter Server or Update Manager Server if the port 9084 is port. From ESXi putty session run the below command, nc -z [VCSA_IP] 9084 Connection to VCSA_IP 9084 port [tcp/*] succeeded! If the above command is not succeeded, please check the 9084 port as mentioned in Step2 and get this port open between ESXi and VC/VUM. Note: Make sure the forward lookup and reverse lookup for vCenter Server is working as expected using nslookup command.If this article didn’t solve your issue: Ask for help here : Click for VMware Communities
