      Good Day

      pfSense version: 25.11.1-RELEASE (amd64)
      CPU Type: Intel(R) Xeon(R) CPU D-1537 @ 1.70GHz
      RAM : 64GB

      HAProxy version: 3.2.7-be4f72d
      Maximum connections: 10000 per process.
      Number of threads to start per process: 1

      I get intermittent errors 502 and 504.
      If I use port 80 (not port 443) for the backend I don't seem to get these errors.
      There are other backends that use 443 that don't have this issue.

      nb. the backends that seems to have a problem are all Debian.

      What could it be...
