Please give me some advise.
When I try to connect with web socket with GSM Modem I get error message “connection was closed uncleanly (WebSocket connection upgrade failed (426 - UpgradeRequired))”
But when I use LAN Connection my program run correctly and can connect.
I use autobahn twisted v15.4 in my client program and use websocket ws java script in server program.
There is additional setting when I use GSM Modem to connect websocket?
