我正在使用 opentok 客户端 JS api OpenTok.js 2.14.6 753045900 来设置视频 session 应用程序。间歇性地，它会向 chrome 控制台抛出错误:
WebSocket connection to 'wss://mantis002-ams.tokbox.com/rumorwebsocketsv2?socketId=12796b11-4174-431e-980f-52c29c32aa0d&attempt=b58d3a4d-7721-4e93-b39b-76224b00864a' failed: WebSocket is closed before the connection is established.

如何正确处理这种情况，因为重新连接似乎在 OpenTok.js 中不起作用？ 当我尝试重新创建 session 时，我收到了
OT.exception :: title: Unexpected Server Response (2001) msg: Unexpected server response. Try this operation again later.
{ code: 2001, message: "Unexpected server response. Try this operation again later.", name: "OT_UNEXPECTED_SERVER_RESPONSE", stack: "Error: Unexpected server response. Try this operat…/static.opentok.com/v2/js/opentok.min.js:23:8742)"}
mixin.js:23 OT:RumorSocket:49 The connection is being terminated because the endpoint has indicated that reconnections are not available. (CLOSE_UNSUPPORTED)
