I am having trouble connecting to our on-prem Business Central OData feeds from Power BI Desktop. Here are the steps I followed:
1) I created a Web Service Access Key token for my own user account in BC

2) I access some OData v4 URL in my browser with my user name & web service access key credentials to confirm it works:

3) In Power BI Desktop, I go to Get Data -> Dynamics 365 Business Central (on-premises) and input the same OData v4 URL as above. It then prompts me for credentials and the same ones do not work:

Same happens when using the standard OData connector.
From another thread on this topic, I am missing two pieces of info that could help in this investigation:
1) "If OnPrem, how are the ODATA web services setup in the Service Tier?"
I don't know what a Service Tier is.
2) Also, you might need to have the Power BI Gateway installed on your server, if your server is behind a firewall and the ports are not open for Power BI to connect to it.
Does Power BI use different ports than the one specified in the URL (7048, which evidently is already opened)?
Thanks in advance for any help.
