尝试将视频上传到youtube API时发生408超时错误

This was working fine yesterday, but fails today. Are there ways I can avoid this? Here is my code: where service is an oauth authenticated service to upload videos, and upload is a valid &youtube.Video. Also, reader is a pointer to the file object of the mp4 video to upload.

option = googleapi.ChunkSize(googleapi.DefaultUploadChunkSize)
call := service.Videos.Insert("snippet,status,recordingDetails", upload)
video, err = call.Media(reader, option).Do()

Thanks for any help.
