Websocket message is not sending

[Surekha95]

I'm trying to send some web socket message when StreamChannelCodecs throws error, but it is not sending and written error as
time="2024-06-06T17:44:17+05:30" level=error msg="write tcp 192.168.124.129:8084->192.168.124.128:63796: i/o timeout" call=Send channel=1 func=HTTPAPIServerStreamMSE module=http_mse stream=demo0

I have updated like this
defer Storage.ClientDelete(c.Param("uuid"), cid, c.Param("channel"))
codecs, err := Storage.StreamChannelCodecs(c.Param("uuid"), c.Param("channel"))
if err != nil {
requestLogger.WithFields(logrus.Fields{
"call": "StreamCodecs",
}).Errorln(err.Error())
//sendErrorMessage(conn, requestLogger, "StreamCodecs")
err := wsutil.WriteServerMessage(conn, ws.OpBinary, []byte{8})
if err != nil {
requestLogger.WithFields(logrus.Fields{
"call": "Send",
}).Errorln(err.Error())
}
return
}
