Issue Unable to open anymore Add or Remove Components or Updates

[PeopleInside]

Server operating system version

Ubuntu 22.04.1 LTS

Plesk version and microupdate number

Plesk Obsidian Version 18.0.44

After try to fix an issue with Monitoring is not working. Ubuntu 22.04.1 LTS now I'm unable to access anymore to Add or Remove Components or Updates.
Seems I cannot anymore install or add components or check for updates.

I'm unable to access to the https://IP:8443/admin/update/product/
because I get

ERR_EMPTY_RESPONSE and after a while:

ERR_CONNECTION_REFUSED

Seems the update option of Plesk is now broken.

I'm looking for a solution.
