Error Message on Power BI Desktop: Web.Contents failed to get contents from _____ (502): Bad Gateway
Hi DMB90
The issue isn't with Power BI itself, but rather with the data source you're trying to access.
A 502 Bad Gateway typically indicates a problem on the source server’s side – for example, it may be overloaded or rejecting the request due to size or rate limits. Since you mentioned the file is over 55 MB, it’s possible that the API or server has limitations on request size or timeout thresholds.
If you can’t filter or reduce the data in Power BI, I recommend reaching out to the support team of the data provider to clarify:
-
Are there any known limits on download size or request frequency?
-
Is there a recommended way to paginate or query partial data?
-
What’s the best way to handle large datasets through their API?
