Issue/Introduction

The following error is returned when adding a site server to the Internet Gateway:

Failed to validate server certificate

You can check and see if the port is opened by using the Powershell Command Test-NetConnection <ipaddress> -port <port> and the results will be something like:

ComputerName     : ServerName
RemoteAddress    : 1.1.1.1
RemotePort       : 4726
InterfaceAlias   : Ethernet0
SourceAddress    : 1.1.1.2
TcpTestSucceeded : True

Environment

ITMS 8.x

Cause

Port 4726 is not open on the Site Server, or or it is misconfigured in IIS.

Resolution

By default, the Internet Gateway and the Site Servers communicate with each other using port 4726.  Port 4726 needs to be bound in IIS using the https protocol and the correct certificate assigned.
