[Personal Gateway Upgrade required] The On-premises data gateway (personal mode) is now available

Hello,

I have been using live stream data for the past couple weeks and everything has been working fine. As of yesterday (8/9/2017) when I try to upload data to the dataset I get a returned 500 internal server error. However I have not done anything different than I have been doing. What could be causing this sudden error? here is the exception that gets thrown:
