If there is an issue with the SSL termination module like it does not find the right certification,

All you need is to regenerate the certs. Just simply run the following commands one by one : 

  1. rm -f /opt/bitninja-ssl-termination/etc/haproxy/certs/*
  2. rm -f /opt/bitninja-ssl-termination/etc/haproxy/cert-list.lst
  3. rm -f /opt/bitninja-ssl-termination/etc/haproxy/haproxy.cfg
  4. bitninjacli --module=SslTerminating --regenerate
  5. bitninjacli --module=SslTerminating --reload
