problem with network manager "connection.autoconnect-ports: unknown property" about operating-system HOT 2 CLOSED

I have come across the same problem while trying to add a VLAN connection to my HA server.
The command that I used is:
nmcli con add type vlan con-name eno1@vlan30 dev eno1 id 30 ip4 10.xx.xx.20/24 ipv4.dns 10.xx.xx.1 gw4 10.xx.xx.1

The error given was:
Warning: nmcli (1.46.0) and NetworkManager (1.44.2) versions don't match. Restarting NetworkManager is advised. Error: Failed to add 'eno1@vlan30' connection: connection.autoconnect-ports: unknown property

I'm running HASSOS 12.3 on an Intel NUC and HA 2024.5.5 with Supervisor 2024.05.1

The error with the version mismatch is coming from the fact that you're accessing the Network Manager backend from nmcli running in a container, so it's not a surprise the versions don't match. While HAOS has a specific version coming from the latest Buildroot (plus eventually some HAOS modifications), the containers use nmcli from the Alpine Linux repositories. A (very dirty) workaround would be to manually install/compile an older version of the nmcli and use that.

However, using NM directly is something that's rather unsupported and discouraged - now that HAOS has ha network ... commands in the CLI, those should be used instead. In case you're missing any functionality there, please file a feature request for that, as it's the way how we should move forward. Closing this, since it's not an OS issue.
