Are you able to consistently reproduce receiving the error prior to market open? I tried your request just now at 6am Beijing time and had no problem retrieving the data.
I think rather than being a function of the time of the day, what you experienced is a timeout from the backend, which happens if for any reason the request processing by the backend takes more than 15 seconds. This is a known issue and it's being worked on. In the meantime the only suggestion is to try the request again when you receive this error.
See this thread for an example.
