Web.Contents error : Access to the resource is forbidden

[andreadak]

I'm trying to connect to a public open data web site for the PA governmental datasets.

One web page is https://www.italiadomani.gov.it/content/sogei-ng/it/it/catalogo-open-data/gare-del-pnrr.html

The page is accessible via browser without any permission requirement (anonymous access)  and from the page some files can be freely downloaded, for instance the Json file at link

https://www.italiadomani.gov.it/content/dam/sogei-ng/open_data_2024/PNRR_Gare-Dati_Validati_v3.json

However when I try to connect to the file with PQ module of PowerBI, I get the following error:

"Expression.Error: Access to the resource is forbidden"

This happens for all files that I tried to download from this site.

Can anyone help me understand how to solve the issue?

Many thanks

Hi @andreadak ,

I've done some testing and found that there may be a setting on the site itself that prevents you from connecting to the site directly via the Web connection method or an M code such as Web.Contents to access the content therein.
I'm trying to connect directly to the Home page of the site using the Web Connector directly:

But still the same error:

If you can't even connect to the Home page, chances are that the site has disabled certain connectivity features.
If you need Power Query to connect to some of these files, you may need to download the file from the site first, and then use File.Contents to connect to the file you downloaded locally:

looks like that website is using a specific httpmanager script to prevent automated access.  Investigate if they offer an API instead.
