Personal Mode Gateway - Key Error

Hi ashleylinkewich ,

1. About personal gateway error:
   • Please uninstall on-premises data gateway, delete related folder here: C:\Users <username>\AppData\Local\Microsoft\On-premises data gateway (personal mode). 
   • Reinstall .Net Framework 4.7.2 or greater then reboot machine. (Download link: .net framework )
   • Install the latest on-premises data gateway (personal mode) version April 2020 (Download link: On-premises data gateway (personal mode) )
2. About enterprise gateway error: The 400 ERROR means a bad http request. Please updata on-premise gateway to the lastest version. (Download link: On-premises data gateway ) If you already have updated the gateway to the latest version, then you can refer to steps below for troubleshooting.
   •  Check if the server is using a proxy and the proxy. Some proxies restrict traffic to only ports 80 and 443. By default, communication to Azure Service Bus will occur on ports other than 443.
   • You can force the gateway to communicate with Azure Service Bus using HTTPS instead of direct TCP. You will need to modify the Microsoft.PowerBI.DataMovement.Pipeline.GatewayCore.dll.config file. Change the value from AutoDetect to Https. This file is located, by default, at C:\Program Files\On-premises data gateway.

   • Restart the gateway and check if the issue persists. 

     • To stop the service, run this command:

       ''' net stop PBIEgwService '''

     • To start the service, run this command:

       ''' net start PBIEgwService '''

   • You may export the data gateway log by selecting Diagnostics and then selecting the Export logs link near the bottom of the page. Reference: Troubleshoot gateways - Power BI.
