I am following along with the tutorial for configuring HAProxy and certificates for internal domains. I am having trouble validating an acme certificate because my whole network by default connects to the internet through a VPN. When I go to validate the certificate it fails because the ip address returned is the VPN ip address and not my local internet provider ip address. I have tried forcing several different addresses out through the WAN but nothing has worked. I have tried the url with a blank and the domain and _acme-challenge.domain.net. I have also tried sending outbound1.letsencrypt.org and outbound2.letsencrypt.org. Nothing has worked. I would be grateful for any advice.
use dns method if your first option is not working.
