If your connections are actually doing stuff in both directions during 
this time, you can notify lws using lws_validity_confirmed(wsi) when you 
saw something that means the connection must be working in both directions

https://libwebsockets.org/git/libwebsockets/tree/include/libwebsockets/lws-timeout-timer.h#n329-349

and it will reset this timeout.

At context / vhost creation time you can set the timeouts

https://libwebsockets.org/git/libwebsockets/tree/include/libwebsockets/lws-context-vhost.h#n728-731

point to a lws_retry_bo_t and set these (in secs)

https://libwebsockets.org/git/libwebsockets/tree/include/libwebsockets/lws-retry.h#n29-30

if you don't, they use the context default which is for ~5min.
