Why error occurs during data downloading?

There are two possible causes.

1. Existing download result inconsistent with new download workflow.
   After data downloading, the data download link of a device during a period is listed in Download > Result. Since we have updated the download workflow, when you download data of the device of the same period for the second time, inconsistency happens, and error may occur. In this case, go to Download > Result and you will see a pop-up window. Click Clear cache and close and then try downloading again.

2. Connection incompatibility with a few ISPs (Internet Service Provider).
   Users of most ISP don’t have this problem. However, error may occur for some of them due to connection incompatibility. This will be less a problem as our cloud service provider are compatible with more and more ISPs. In this case, try to use the internet service provided by another ISP.

If error still occurs, please contact us.
