Browser Based Launcher sessions disconnect unexpectedly when using a Nginx Reverse Proxy

[support]

A user has reported an issue with the browser based launcher, where after establishing either a RDP of SSH session, the tab that the session is in seems to close unexpectedly.  This happens at around the 2 minute mark into the session.

 

The customer came back to us for a fix for this, which I've quoted below.  Thanks to our customer who provided this feedback, if you are reading this:)

 

The issue with the remote session launcher closing after a few minutes of inactivity was reverse proxy related. We are using NGINX as a reverse proxy. Since your browser-based remote sessions use WSS, an upgrade instruction was needed to get the launcher working (proxy_set_header Upgrade $http_upgrade). After that, remote sessions worked, but they would close after a short period of inactivity. This timeout has been increased with the (proxy_read_timeout) instruction. These two config lines will be needed if users would like to use browser-based remote sessions with an NGINX reverse proxy successfully. Everything works great now.
