{"errMsg":"sendSocketMessage:fail fail:send wcwss return fail code:-1"}

最近websocket老是出现错误，代码很简单，如下，上面是错误信息

socket = wx.connectSocket(info);
socket.onOpen(...);
socket.onError: (res) => {
                log.error("WS onFail - 2,", res)
                console.log("WS onFail - 2,", res)
                wx.showModal({
                  title: '网络错误',
                  content: '打开消息服务失败，是否重试？',
                  success: (res) => {
                    if (res.confirm) {
                      wx.reLaunch({
                        url: "/" + url.getCurrentPageUrlWithArgs()
                      })
                    }
                  }
                })
              }
            })
