You are unable to connect to the vSphere Client interface for your SDDC.

Problem

When you click the link on the connection tab to open the vSphere Client interface to vCenter Server, your browser reports that the site cannot be reached.

Cause

By default, the management gateway firewall is set to deny all traffic between the internet and vCenter Server. You must create a firewall rule to allow traffic to the vCenter Server.

Procedure

Create a firewall rule as described in Set Management Gateway Firewall Rules
