Service Bus message broker services wouldn't start

Question

I need assistance with my Sharepoint 2016 (on prem) installation. I have 2 servers in my farm, an App server and a DB server. The Service Bus message broker server went into 'starting' and remains there. I've tried several solutions: I stopped it and restarted after restarting Fabric host, workflow manager and service bus gateway services.
I've left the farm and rejoined again, but it gets stuck where it needs to start the service bus message broker. So I uninstalled Workflow manager completely and restarted from scratch with new port numbers (in case it was used by another process) But still the service bus message broker will not start. What else can I try - any suggestions?

Answer 1

Please check whether the Service Bus ports are used with other web applications or blocked by firewall mentioned at following article:

Answer 2

Thank you, I did the check on the ports. But the IT confirmed they installed a cyber security software that check for vulnerable ports and automatic block them. The software blocked the service bus ports. They changed the setting and the Service Bus started without any problems.
