“No host found” after RHEL patching

After patching the OS with RHEL updated packages I have an issue receiving no host found ,
although I can see the hosts lists.
Anyone had this issue?
Do I need to run something on the Foreman database?
Foreman version is 3.8.0

It’s best to run foreman-installer after any package update. Sometimes files need to be removed which have been restore by the update.

It worked, many thanks!
