PFSense with HAProxy & Let’s Encrypt using Standalone HTTP or Standalone TLS-ALPN server give following error “Cannot negotiate ALPN protocol”
Just wondering if anyone tried this as I have a google domain and has issue with automatic renewal. I notice if I have HAProxy enable while trying to run the renewal there were issues and the dates never update during the renewal. Only when I manually disable haproxy and run the renewal does the renewal seem to work.
FYI if i create a new certificate for a new subdomain or domain i run into the same issue until i turn off HAProxy. I do turn on HAProxy back on afterward as i need it.
Turning off HAProxy like below works (see image below). Not sure if the 443 port is share between HAProxy and Let’s Encrypt so I think that is the issue but not sure…
