I am trying to create a new connection in PowerApps to our Business Central (on-premise) using Odata Web services. I am replacing the localhost with the external public IP address in the URL that I got from IT so that it looks like the following - http://99.999.99.999:7048/BC140/OData/Company('XYZCompany') After submitting my credentials I get the following error from Powerapps - status 503 Service Unavailable. When I plug the exact same address into any browser, I am prompted for my credentials and successfully connected to the service. This leads me to believe, that the problem is with PowerApps, because clearly the service is not unavailable nor are my credentials incorrect. Is anyone else having this problem? I would love to hear how you solved it, or maybe it is totally a PowerApps bug.
