Hi,
I've installed the Power BI Gateway service successfully, configured a gateway, created a datasource and everything looked good.
I changed the service account that runs the Power BI Gateway service from NT SERVICE\PBIEgwService to a domain service account, I refreshed the connections in app.powerbi.com, I get the following error:
Unable to connect: The gateway is either offline or could not be reached.
Activity ID: 67a30327-2fc0-376d-0505-a0ff91a1e5bc
Request ID: 4980dee0-d7ff-4c01-a299-4bfbd961b7d9
Cluster URI: https://wabi-west-us-redirect.analysis.windows.net
Status code: 400
Error Code: DM_GWPipeline_Client_GatewayUnreachable
Time: Thu May 05 2016 12:08:12 GMT-0700 (Pacific Daylight Time)
Version: 13.0.1100.480
I've restarted the service (successful, no errors in event logs), I've ensured the domain service account has the "log on as a service" permissions, I've uninstalled, downloaded the latest GatewayServiceInstaller, installed it, it worked when running under NT SERVICE\PBIEgwService but breaks when I change the service account to a domain level account.
thoughts..?
