Login from Moodle

I've a problem.

If I log in using Joomla form, I'm also loged in in Moodle. But if I log in from Moodle, I'm not loged in, in Joonla.

Do you know why could be happening this?

Do you have green checks for everything inside your system health?

What are the browser urls when you login from each way?

Yes, everything is green.

Some info more:
Starting I'm logged out from both services.
I make log in in Joomla.
I open Moodle, and I'm also logged in.


I log out from both services.
I make log in from Moodle.
I open Joomla site and I'm not logged in.


Also there is an other thing that is not working. If I register an user from Joomla, but delete it from Moodle, user disappears from Moodle, but still persists in Joomla. I've Sync users to Joomla enabled. But if I delete user using Joomla, it disappears also from Moodle.

Thanks!!
