Hi,
> Thank you. So check.txt is just an empty txt file? Yes. You can test this with curl. Your configuration expects the following request to return 200 OK: curl -I http://192.168.88.97:80/check.txt If this is not happening, either because the file doesn't exist, HEAD request are not allowed or the Apache requires a Host: header due to a vhost configuration, then haproxy will mark the server down.
