The web console does not function for virtual machines in the vCenter vSphere Client

Products

• VMware vCenter Server

Issue/Introduction

• ESXi hosts' FQDNs are used to manage the ESXi hosts in vCenter.
• The web console functions for VMs in the ESXi vSphere Client but does not work in the vCenter vSphere Client.

Environment

VMware vCenter Server 7.0.x
VMware vCenter Server 8.0.x

Resolution

1. Verify the vCenter DNS settings and ping the ESXi FQDN from vCenter as outlined in the KB article: Resolving ESXi Host Disconnects Caused by DNS Resolution Failures in vCenter Server

2. If the ping fails, resolve the DNS issue or add entries for the ESXi hosts in the /etc/hosts file.

e.g. <ESXi_IP_ADDRESS> <ESXi_FQDN>

3. Verify connectivity from vCenter to the ESXi hosts' TCP port 902. If it is not open, check the ESXi/vCenter firewall settings and involve the network team to investigate any firewall issues. 

nc -zv <ESXi_FQDN> 902
