Describe the Bug

The admin account fails to handshake with all peers using the VPN client.

Tested it on Windows, Linux, Android and results are all the same.

All other accounts are perfectly fine and handshake without issues to all peers.

Tested on multiple networks including the same network as pangolin server.

This was not always a problem, it started when I updated all containers to the latest release, I admit I cant remember which version I was on before when it worked but I had not updated since about December 25.

Environment

OS Type & Version: Ubuntu 22.04, 24.04, Windows 10 & 11, Android 15
Pangolin Version: 1.15.2
Gerbil Version: 1.3.0
Traefik Version: 3.4.0
Newt Version: 1.9.0
Olm Version: (if applicable): N/A
Pangolin VPN Version: Android(0.1.5), Windows(0.5.1), Linux CLI(0.3.1)

To Reproduce

Connect using Pangolin VPN client on any platform with the Owner/Admin account, observe that status is disconnected to all sites, and logs show all peers failing to handshake

Expected Behavior

Expect to connect and be connected to peers with successful handshake, as happens with any other user I create.
