wx.uploadFile上传失败？

wx.uploadFile上传视频，经常碰到上传失败：

"error":{"errMsg":"uploadFile:fail Write error: ssl=0x72b0093688: I/O error during system call, Software caused connection abort"}
或者
"error":{"errMsg":"uploadFile:fail Read error: ssl=0x6efbcc7d88: I/O error during system call, Software caused connection abort"}

这个问题原因是什么？有什么办法可以解决吗？
