HAProxy is an amazingly powerful tool, and you're using it like a brick. What's more, instead of building a wall with that brick, you're burying it in the mud and saying "Tadaa".
The irony of having HAProxy in place to load balance/failover between two web servers, but then stopping HAproxy every time you need to renew a certificate is amazing.
