ping pong in version 4.4.1 not work Automatically

[elelemy]

the server send ping to client only once and the client responds but after that the server doesn't ping again causing timeout and disconnection

the server option is
{
path: "/socket/events",
transports: ['websocket'],
allowUpgrades: false,
pingInterval: 10000,
pingTimeout: 25000
}

the client option is
{
auth: {token: accessToken},
transports: ['websocket'],
path: "/socket/events",
upgrade: false,
autoConnect:true
}

Hi! That sounds weird. Are you able to reliably reproduce the issue?

[elelemy]

server sends ping and browser responses with pong just one time .
Then , after pingInterval + pingTimeout ,it opens a new websocket connection.

From the screenshot above, It seems you have two different clients, one with EIO=3 (Socket.IO v2) and one with EIO=4 (Socket.IO v3/v4). Could that explain the issue?
