We set it to dummyName because we’re specifying the server name using the ProxyCommand field instead. And we put the HAProxy in front of the REST API server. Step 3: Configure HAProxy to Accept Encrypted Traffic To configure HAProxy to accept encrypted traffic for your subdomain, follow these steps: When setting up SSL termination with HAProxy, you need to combine fullchain. By default HAProxy adds a new extension to the filename. - a FastCGI gateway : FastCGI can be seen as a different representation of HTTP, and as such, HAProxy can directly load-balance a farm comprising any combination of FastCGI application Haproxy terminates the SSL then, instead of forwarding the unencrypted traffic to your backend on a HTTP port, try forwarding it to a HTTPS port on the backend and wrap that in a self signed cert. It seems to work correctly, as the landing page displays correctly. I would like to make a re-encryption on the backend side, but the ssl/tls check gives me the famous ‘Layer6 invalid response: SSL handshake failure’, in tcpdump ‘Unknown CA (48)’.

HAProxy Runtime API Add a CRT list to your HAProxy Enterprise configuration file on a bind line: haproxy. oneadr. I also don’t see how that would make sense, why would you secure the proxy → backend layer and leave the client side unprotected, that doesn’t make sense to me. We will not need a separate SSL/TLS termination service because HAProxy will do that termination for us. I would strongly recommend to not do this however. I won’t be able to tell you “sure, this flag X in configuration line Y in haproxy”, because this is not a haproxy related problem, but a problem with your environment.
