Does this work in all cases, or only when the proxy and Mattermost server are on the same machine?
For example, if the proxy is on 10.10.10.1 and the Mattermost server is on 10.10.10.2, should the ListenAddress be 10.10.10.1:8065?
That is, should the ListenAddress be set to the address of the machine that hosts the proxy, or should it always be localhost:8065?
