Can Hangfire be restarted without code

We are using 1.6.17 (under IIS and SQL server) in an old version of our product and are finding that when we delete a running job from the queue (using the hangfire scheduler console) it doesn’t then start processing the rest of the queue.

The workaround for this is to restart hangfire, but the only way to do this I know is to restart the app-pool it is in which is not ideal as our application is also in it.

On searching I can see there are programmatic way to tell HF to restart but as that isn’t an option for me was wondering if they was an API call or whatever I could send to do trigger it?
