status.dat and retention.dat missing in Nagios Core 4.4.10

[sawolf]

Not reproduced in-house yet. Making this issue to track https://support.nagios.com/forum/viewtopic.php?t=65943&sid=d91711b249745092ac546b9f1ef5655e

From the thread, appears to be a follow-up issue from the resolution for #861. User sees that retention.dat and status.dat are not created when restarting Nagios Core. After setting check_for_updates=0, both files are created properly.

This issue is resolved when the user can use status and retention information without disabling update checking.

Ubuntu Server 22.04 LTS
Nagios Core 4.5.0
Nagios Core server and clients are fully isolated (no access to external resources)

Can confirm the problem still exists

If the following files are missing: "status.dat" and "retention.dat", then the Nagios service starts but will not work properly. Status reported as Active, but no service checks are performed.

No records about any connectivity problems to the dedicated endpoint can be found in the "nagios.log" or "nagios.debug" log with the following parameters:
debug_level=-1
debug_verbosity=1

After setting check_for_updates=0, both files are created properly.
