Hi, thanks for your bug report!
From the version strings I conclude that this is happening on a Ubuntu
22.04 LTS ("Jammy") system, can you confirm this?
The netplan.io version 0.106.1-7ubuntu0.22.04.4 that you mentioned above
was released in June 2024, about a year ago. If you say the issue
happened earlier this year (2025), this is probably unrelated.
But:
There is a major new Netplan version in jammy-proposed (v0.107), have you
already tried if using that is making any difference?
(https://launchpad.net/ubuntu/+source/netplan.io/0.107.1-3ubuntu0.22.04.2)
Also, can you please show the contents of Netplan runtime directories after the
systems lose their connection and provide journalctl logs, potentially with
systemd-networkd debugging enabled [1], to see what's going on.
$ tree /run/systemd/network
$ tree /run/NetworkManager/system-connections/
$ journalctl -g systemd
