Hi,
I'm using sockjs with rxStomp to open a WebSocket and download some Realtime files. in an unexpected behavior ,some times I'm getting failed: WebSocket is closed before the connection is established cause of transport time out . after some investigation i found out that the failed connection have a long stalled/blocking time for about 6 hours which causing transport timeout .

any help please why there is a long connection start causing this issue ?
Thanks,
Marwa
