Hello, I use the Flint 2 with the 4.5.5 version.
It doesn’t matter whether Nordvpn is via the implemented app or Manuel VPN.
Not even with Surfshark.
Tried everything OpenVPN or Wiregaurd with no success.
If I play a version 4.5.3 it works but then there are WiFi problems
Please post your log files so we can understand whats going on.
There is no known issue with WG VPN in 4.5.5; at least not yet.

Does work ip6 wireguard? I thought vpn working only ip4 
Did I got right that on 4.5.3 everything worked?
VPN yes!! at 4.5.3
but
Wifi problems.
With the VPN I also noticed that despite changing servers several times with NORDVPN and different protocols and together with Nordvpn, I never got over 90 to 110 mbit. With a 200 mbit line.
With Surfshark I can get up to 175mbit
But they are no longer at 4.5.5 until now. But VPN problems.
While upgrading: did you select that the current settings should be preserved?
No, I always do a fresh install without any legacy issues.
But I also tried from 4.5.3 to 4.5.5 and retaining data doesn’t help either.
I noticed your screenshot wgclient does not support protocol. Could be that problem?
Nah, that is normal.
That should be fine, since gl-inets version is different than the normal OpenWrt version.
But i dont see a lan interface in that screenshot, though theres a mentoin theres one in the logs.
So that makes me wonder if the router is set into repeater modus, and if or the lan interface is needed for the wgclient script.
That should be good 
, so this is not the issue.
Edit:
Can you post the config from dhcp perhaps?
I wonder what the ranges are, i see some possible illegal/invalid start ips here like: 192.168.9.100
192.168.50.15 - 249
this is the set area. Everything is identical to 4.5.3
Hmm , sounds ok to me but just verify in luci to be sure.
I want to see the limit it shows there, if that combined with 192.168.50.15 points above 254 its wrong 
, might not fix your wg issue directly but it insta alerted me 
This can be done in luci → network → interfaces → lan (edit button) → dhcp server (tab).
But it wouldn’t matter, even with a completely new install without any settings, the problem still exists under 4.5.5
Yea they look fine, it could still mather if it was wrong because the broadcasting would not work as expected, but .255 is the broadcast address so.
I think the contents of network, firewall and wireguard are needed just to be sure theres nothing wrong, just make sure you dont disclose any private info like public ip👍
Perhaps it is a new issue in the firmware
Try reset vpn? I think problem wrong private key I mean start over create vpn server/client.
Tried everything.
The same settings work under version 4.5.3, so it seems to be due to version 4.5.5.
Various providers were tested and almost all the settings that I could make
