Nothing to do with dhcp here. Reassigning to proper component

and another one journal screenshot. starting from line, I guess, "grace period expired"

Can you please do the following (as root user):
- edit /etc/NetworkManager/NetworkManager.conf and set level=TRACE in the [logging] section
- set "RateLimitIntervalSec=0" in /etc/systemd/journald.conf
- reboot
- wait that the problem happens again
- attach the output of 'journalctl -u NetworkManager -b' to this bugzilla
After attaching the journal log, you could change the DHCP plugin
used by NM to solve your issue. To do this, set 'dhcp=dhclient' or
'dhcp=systemd' in the [main] section of /etc/NetworkManager/NetworkManager.conf.
Then restart NM with 'systemctl restart NetworkManager'.
Thank you!

Unfortunately the log doesn't fit in one screen. Could you instead do:
journalctl -u NetworkManager -b > log.txt
and attach the log.txt file? If you didn't reboot since then, you don't need to perform again the previous steps.

I didn't rebooted. changed to dhcp=system after uploaded last screenshot (this helped). complete log, includingly screenshoted timings, is in attachment.
