I had Site Connector MemoryMQ installed on the server, it worked correctly for some time, but after some time an error was displayed that it was not Validate. I tried uninstalling, reinstalling and setting up the MemoryMQ Site Connector in the administration, but even when creating a new Site Connector it is not possible to validate it.

An error dialog appears
Failed
The connection to Site Connector failed. There is a possible port/hostname issue.

Please, can someone advise where to look for the cause of the problem and how to validate the Site Connector so that it can be used?

Hello Martin,

First, I strongly recommend using RabbitMQ as your messaging application, as it operates stably with ISVPV/Secret Server. Other MQ applications can crash due to excessive RAM consumption; restarting the service, or sometimes even restarting the application server along with it, can resolve the problem.

If the crash is severe and its impact is irreversible, a reinstallation may be necessary, but you must ensure it is uninstalled correctly first. Furthermore, the relevant ports for the site connector must be open on the application servers (RabbitMQ uses port 5672), and the accessibility of the MQ services must be verified.
