Azure Graph : An existing connection was forcibly closed by the remote host.

[jasonrutherford]

Hi all,

When running a custom connector in a small environment against azure graph API I receive no errors. I then tested the connector in a larger environment and I receive the following:

OLE DB or ODBC error: [DataSource.Error] OData: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host..

I've tried limiting the rows returned, which somewhat works, but the results have been inconsistent. Any assistance is appreciated!

Does your company have hourly API call limits for the graph API?  Have you tried adding a delay in between calls?
