After leaving it plugged in for some minutes i relogged back in using Luci so it would get added to the system log so you see nothing else is being done.

Can you please try adding option checkup_interval 10 to that VPN interface in /etc/config/network. It tells netifd to wait that many seconds to check if the interface is up since last setup attempt and retry if it's not the case. The option is documented at https://github.com/openwrt/packages/tree/master/net/xl2tpd#uci-options . It should fix the issue.
The other thing worth noting is that it seems wan down and up event did not occur along with the unplug/re-plug action (link status changed from 0x18 to 0x8, then again to 0x18). It seems that link status of switch port do not current translate to interface up/down status of switch cpu port.

5 years ago @yousong Sorry for my late reply, i will check this option this weekend to see if it fixes the issue.
Is there anything we can do (workaround) for the up/down status of switch cpu port?

You can write script with swconfig command to query link status of the wan port and bring up/down eth0.2 interface. But it's just too hacky to worth going further.
I wonder maybe switchdev drivers can help in this situation, but that requires driver and userspace rewrite.

5 years ago The problem, checked already on all openwrt that on stable that on snapshots: I pull out a router from a network, I connect, there is no network on L2TP I do restart through the interface in a router, a network on L2TP is I reboot L2TP connection in the router interface, the network also is
In what there can be a problem that the router does not connect L2TP after disconnection from a network?

One thing worth adding is that MAYBE after unplugging the l2tp tunnel session will detect timeout and trigger teardown and reconnect.
Maintainer: @yousong Environment: (RAMIPS, HLKRM04, OpenWrt 18.06.2)
Description:
L2TP VPN won't autoreconnect, if WAN cable gets unplugged and gets plugged back in after you receive the message: "daemon.debug xl2tpd[1062]: Unable to deliver closing message for tunnel 20224. Destroying anyway. in system log" in System Log
Everything is build from the default feeds and updated yesterday. Earlier 18.06.1 had the same issue.
Extra question: Would it be possible to have a default l2tp VPN connection added on firstboot? Would allow for easy configuration when replacing devices is needed by non technician.
