Connection auto Closed after about 5 seconds when inactive (NO INPUT)

[zhongkaiwen]

When I start a new client and immediately type some basic commands, it works just fine. However, the client tells me "Connection Closed" after a while if no commands is put in the browser.

here is the log:

This may be caused by 26f8b17, ttyd 1.4.0 requires libwebsockets 2.1 to have ping-pong support. What's your libwebsockets version?

[hanwckf]

update your libwebsockets

[zhongkaiwen]

@tsl0922
mingw64/mingw-w64-x86_64-libwebsockets 2.1.0-2

[zhongkaiwen]

@hanwckf
I update libwebsockets to version 2.1.0-2 and json-c to version 0.13_20171207-2, but it still doesn't work

[tsl0922]

Clear you browser cache (or use a private window) and try again, ttyd 1.4.0 browser client won't send a message with type 2.
