Changing the Hostname of Carousel server breaks bulletin rendering

Applies to

  • Carousel 6.5.0+

Symptoms

  • When attempting to create/edit dynamic bulletins you receive an error "None of the specified endpoints were reachable"
  • Error in the TRMS Event Log: "DynamicUpdater: ā€œError while updating dynamic pages: None of the specified endpoints were reachable" orĀ RenderService: ā€œRenderer creation error (attempt 61): None of the specified endpoints were reachableā€
  • The RabbitMQ Service appears to be running, but is not listening on port TCP 5672

Cause

The RabbitMQ service is unable to communicate with its endpoints because the hostname of the computer has been changed since Carousel was installed.

Resolution

While logged in under the same account Carousel is run under, from an elevated command prompt run

"C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.3.4\sbin\rabbitmq-service.bat" install

Then change the RabbitMQ service to logon with the Local Account and restart it.

Additional Information

This will only occur when the Hostname of a computer is changed after Carousel 6.5.0+ has been installed.
