DNS in configs invalid after running update-users

[dkim19375]

(From #14613)

Describe the bug

After following the steps in https://github.com/trailofbits/algo#adding-or-removing-users, the configs including users that were already added generated a DNS IP that, when running ping, would not respond.
However, the IP I had before update-users did work, and still does work.

To Reproduce
Haven't attempted to reproduce! This may not be the root problem; it's probably some coincidence?
Steps to reproduce the behavior:

1. Run update-users using https://github.com/trailofbits/algo#adding-or-removing-users
2. Try new configs
3. VPN won't work due to the DNS IP being invalid

Expected behavior

DNS IP not being invalid

Additional context

config.cfg (only thing removed is the users section): https://pastes.dev/wD3YVPYhHm
Note: The DNS IP changed from 172.29.186.253 -> 172.28.118.124

I don't have the log anymore
