Could not connect with scheduler

I downloaded the scheduler card from hacs, i have the entity “Scheduler Card update” of it, but when i add the card it says “could not connect with scheduler”

As stated in the card repo…

… that card requires the Scheduler custom compnent, did you download and install that as well?

after a few hours I uninstalled everything that has to do with the scheduler and reinstalled, it worked and everything showed up
