Description

During testing with a backend HTTPS server, I wanted to test if the SSL health check would work; it did not.
So, I decided to switch back to none instead.

When I switched back to none, saved and applied settings, the service reported that this server was down still.
(haproxy, if it determines a server is down, automatically serves a 503 regardless if the server is actually serving pages or not.)

So, I was getting 503 errors when attempting to browse to my backend server through haproxy.

I spent about half a day troubleshooting and at the end I just cloned my backend configuration and pointed the frontend to the clone; it worked!

It seems that switching from SSL health checks to None may not actually write the configuration for haproxy correctly.
