Developer System Administrator

On-Premises only

Description

Coveo for Sitecore uses a specific series of ports to communicate with CES. In a set up where Sitecore and CES are on different servers, you need to ensure that all ports used by Coveo for Sitecore are open on the CES server.

To do so, we use the telnet command from the Windows Command Line Tool.

Environment

  • Coveo for Sitecore 863+
  • Troubleshooting
  • Ports

Explanation

A closed port can lead to various issues such as:

  • Error message at Indexing time
  • No refresh of the Coveo Index
  • No Search results are returned
  • Error message in the Search Interface

Resolution

  1. You need to have Telnet installed on your Sitecore Server.
  2. On your Sitecore server, open Windows Command Line as Administrator.

  3. Use the telnet command with the following syntax: telnet <CES_SERVER_NAME_ON_THE_DOMAIN_OR_IP_ADDRESS_OF_CES_SERVER> <PORT_TO_CHECK> (Replace with the appropriate port number as per the table below.)

You need to change the Port used by the Queue in RabbitMQ before changing it in the Coveo.SearchProvider.config file (see RabbitMQ Configuration).
