Can you show the output of certbot certificates? Because as far as I can see, you've got valid certificates from December 2020 for all your mentioned domains (and a test subdomain it seems):
Also, I'm interested in the script /root/haproxy_letsencrypt/concat_certificate.sh.. What is actually using the (wrong) certificate? Does HAProxy function as the TLS endpoint? Or Apache? Because your site says it's server is Apache 2.4.18.
