That would suggest you are also not receiving PING’s and not sending your own PING’s and likely got DC’ed but your code
So, you have PING/PONG timed out and need to reconnect to to a lost connection.
Twitch sends a PING and you need to reply to it with a PONG.
if you’ve not PING/PONG at least, say, once per minute, send your own PING to test the connection and if no PONG reconnect.
A Reconnect is a request for you to restart/reconnect to Twitch chat as the server(s) are restarting, which doesn’t happen very often (and won’t/shouldn’t of done over the last 4 days due to thanksgiving holiday)
