Volumio not update

I’m writing here not knowing where to put my post. maybe my Volumio has some problems, it no longer updates the OS rev which stops at 3.616 (Feb 13, 2024). online there is rev 3.631.
it’s normal? how can I solve it?
my Volumio run on rasberry PI 4 - 4gb.

Thank you.

please post a log when you search for an update in Volumio System and it fails.
