No network after uninstall of Tailscale Addon

[TPGLLC-US]

Problem/Motivation

I installed the tailscale addon and HA node would come online for a few seconds and disappear. I was not able to access home assistant via my tailscale network. I uninstalled the addon and now My HA VM has no local networking. I cannot access my home assistant web ui.

Home Assistant OS v 8.2024 Proxmox v8

Expected behavior

Uninstalling the addon should revert network settings to what they were prior to the addon being installed.

Actual behavior

Home Assistant VM has no network.

• I reviewed all network settings on proxmox
• Other VMs and LXCs are working
• Tried changing dns server from ha cli
• Tried restarting NetworkManager
• Tried deleting nmcli connections NetworkManager
• Tried adding connection
• nmcli devices show enps018 as unmanaged and will not add to managed
• tbh I've been working on this for 2 days now and I am at the end of my rope.

Steps to reproduce

Install the tailscale addon in an HAOS Proxmox VM and uninstall it

• Turn on an off the DNS option

Fix

After hours of troubleshooting heres the solution for Home Assistant Device unmanaged network device that cannot be switched to managed

Boot home assistant into rescue mode

Start NetworkManager systemclt start NetworkManager

Set device to Managed nmcli dev set <deviceName> managed yes

Exit the rescue terminal exit

Wait for home assistant to start there will be an error

Repair supervisor ha supervisor repair

start core ha core start

You should now have home assistant operating system running again

Without logs it's hard to say anything about what happened. You wrote "Turn on an off the DNS option", the DNS option is default "on", you can disable it with adding accept_dns: false to the add-on config. But this seems to be a Tailscale issue, because the add-on doesn't modify the host's networking too much, nearly everything is done by Tailscale.

Update: Use sg. like ha ad logs a0d7b954_tailscale --lines 1000 to see the logs far in the past.
