Scheduler Jobs Not Running

Did a clean install this morning on a VPS, scheduler does not send out emails but if I send manually the system sends.
Have tried bench doctor etc but cant find why scheduler does not run automatically
Used this to diagnose -

-----Checking scheduler status-----
Workers online: 3 ( Does any one know what (3) means) ? If anything…

ERPNext: v13.12.1 (version-13)
Frappe Framework: v13.12.1 (version-13)

did u find any solution?

i had to redo my install then everything worked but it must have been in my setup , couldn’t pin point exactly …
