Yup, got it all solved after 2 hours. Searched this forum up and down and of course, stumbled on the solution post after posting mine.

Thanks for this. Had the same issue, seems to have fixed it!

Had same issue, this post got me fixed:

So I'm not quite sure what I did wrong. Wireguard (through the Settings>VPN Manager) was working fine for the last few weeks. I went to change some settings in order to allow custom IPs on Docker. I changed "Local Server uses NAT:" to No and changed "Host access to custom networks" to enabled. I setup a static route in my router to send VPN subnet traffic to the server's IP. Now I can no longer activate (slider at the top) the VPN. I fully deleted all peers and the tunnel itself and tried reconfiguring. What I've noticed is that when I create the tunnel, I can activated it. As soon as I add a peer and hit apply, I get the "Peer update required" notification. After, I cannot activate the VPN. Slider just defaults to inactive. Running UNRAID 6.11.1
