Why does celery works with "--concurrency 1 -P solo" and not without?

When I use :

celery -A FAM worker -l info --concurrency 1 -P solo

I can run my tasks from celery.

when I use :

celery -A FAM worker -l info

It doesn't work. But I cannot understand why. I see there is a difference : "16 (prefork)" vs "1 (solo)". What is the difference ? And why does the solo works and the other does not ?

The issue was that Celery does not support Windows since version 4, and so running it on Windows can give issues. As it is with concurrency.

Based on this article I could solve this issue by using Eventlet.

pip install eventlet

And when starting the celery worker:

celery -A FAM worker -l info --concurrency 4 -P eventlet
