Using Nginx as a reverse proxy with persistent connections enabled, CWMP logs show "invalid session."

look at this:

Invalid session with Apache proxy

This happens when the proxy shares the same upstream TCP connection for multiple TR-069 sessions. Genie caches data for an active session in memory (tied to the connection) so you need to configure the proxy such that TCP connections are never reused. I don’t remember how I used to do that Apache. Try the opitons ‘disablereuse’ or ‘stickysession’.
