Handshake OK but Internet doesn't work for NEW users

[dkim19375]

I used https://github.com/trailofbits/algo#adding-or-removing-users & rebooted to add a new user.
When running sudo wg, it says:

  latest handshake: 2 seconds ago
  transfer: 1.41 MiB received, 48.32 MiB sent

but the internet does not work.
However, the internet works fine on another user that was already in the config

It seems like it even received the handshake response, but I still can't connect to the internet...
I have also tried on multiple devices
