Hello. If you have some connection troubles with NetworkManager 1.22.2, it is a known issue.
To fix it - until a new major version is released - you have to modify /etc/NetworkManager/NetworkManager.conf add this:
After this, a little service restart:
sudo systemctl restart NetworkManager
Official fix let think it is a dhcpv4 bug: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/commit/b93fcddfdfa97d2690524a9ab3c681a2caf5996a
