Expected behavior

WebSocket client's connection stays open for multiple minutes and is reused for sending multiple WebSocket messages

Actual behavior (suspected bug)

Every few seconds the client connection disconnects with this error:

E (83821) websocket_client: esp_transport_connect() failed with -1, transport_error=ESP_OK, tls_error_code=0, tls_flags=0, esp_ws_handshake_status_code=101, errno=119
