After upgrading from v4 to v5, Hangfire no longer receives jobs

I upgraded today from v4 to the current version v5.5.3.

However, jobs are no longer arriving in Hangfire. This means that when I run a script, it only appears with a status queue and doesn’t appear at all in Hangfire.

Version v5.5.3
Platform IIS
Installation method: ZIP

For the queued job, can you click the job to go to the job page and then click on the Job Dispatcher button? It should have some info about why it isn’t queuing the job.

After I wasn’t activated here, I submitted a ticket last week, which then resolved the issue.

What was the “fix”?
