UserData socket closes every 2 minutes

[jokaorgua]

Hello. I have a strange issue with UserData websocket
I start it like this

for{
     futures.WebsocketKeepalive = true
    doneC, _, err := futures.WsUserDataServe(listenKey, userDataEventHandler, errorDataEventHandler)
    <-doneC
}

when I run it from my laptop everything is ok.
But when I try to run from server I get disconnects every 2 minutes. (error in console (*net.OpError)(0xc0004a2050)(read tcp XXX.XXX.XXX.XXX:36094->13.112.178.104:443: use of closed network connection))

Any help and ideas would be appreciated.

P.S. I do not see a way to send 'ping-pong' by requesting balance through UserDataStream ws connection (https://binance-docs.github.io/apidocs/futures/en/#websocket-user-data-request)

the most interesting thing that I've tried from another server (different hoster, different location) and it works okay like from laptop

so after a huge amount of tests I've figured out that binance has some kind of problems with vultr japan DC (vultr is my hoster). It closes connection after 2-3 minutes since the last data timestamp sent through this connection.

So the ability to request balance or account data through UserDataStream would be wonderful. This will keep connection alive.
