Unexpected Multiple Hangfire Servers on Live Environment

Questions

Hello,

I’m hosting the site on Umbraco Cloud. When inspecting the Hangfire Dashboard under Servers, I noticed that:

  • In Development, only one active server is listed (as expected).
  • In Live, there are two active servers displayed.

The Hangfire Dashboard displays server information including name, workers, queues, started time, and heartbeat. (Captioned by AI)

However, according to Umbraco Cloud support, we only have a single web app instance, not a load-balanced setup.

Do you have any idea why a second Hangfire server might be appearing? We’ve been experiencing issues with scheduled jobs — retries are shown as triggered in the dashboard, but nothing actually executes. In some cases, the scheduled jobs don’t trigger at all.

I suspect this may be related to the presence of the unexpected second server.

Thanks in advance for any insight you can provide.

NOTE: We have recently upgraded from a Shared Hosting plan to a Dedicated Professional 1 plan.

Best regards,
