Hi @Anonymous ,
If I understand correctly, it seems that you can't connect to Azure Synpase Analytics in Power BI Desktoop. There could be several reasons why you’re unable to connect to Azure Synapse through a proxy in Power BI Desktop:
1. The proxy authentication server on your network blocking the web requests issued by Power BI Desktop
The option1: Ask your network administrator to add the following domains to the allowed list on the proxy authentication server: app.powerbi.com, api.powerbi.com, and domains in the *.analysis.windows.net namespace. If you are using a government cloud, you can add the following domains to the allowed list: app.powerbigov.us, api.powerbigov.us, and domains in the *.analysis.usgovcloudapi.net namespace.
Add Power BI URLs to allowlist - Power BI | Microsoft Learn
The option 2: use system default credentials for web proxy
Using default system credentials for web proxy
2. Authentcation problem
Please make sure that you apply the suitable authentication method and the correct credential info
3. The version of Power BI Desktop
Please update the version of your Power BI Desktop to the latest one.
