Hi @Raja Khan

Thank you for posting your query!

The error ERR_CONNECTION_CLOSED typically indicates that the connection to the server was unexpectedly closed. Given that the new Microsoft Purview portal works on your personal computer but not when accessed from a VM behind an Azure firewall, the issue might be related to network configurations, firewall settings, or other security policies in your Azure environment.

Here are some steps to troubleshoot and potentially resolve the issue:

Network Security Group (NSG) Rules - Ensure that your VM's NSG allows outbound traffic to the necessary endpoints. Verify that there are no rules blocking the traffic to purview.microsoft.com or other related Microsoft services.

Azure Firewall Rules - If you're using Azure Firewall, check the application and network rules. Make sure that it allows outbound connections to the required IP addresses and ports used by the Microsoft Purview portal.

DNS Resolution - Double-check that the DNS settings on your VM are configured correctly and can resolve purview.microsoft.com and related URLs.

TLS/SSL Inspection - If there's SSL/TLS inspection enabled on your firewall, it might be interfering with the connection. Consider temporarily disabling this feature to see if it resolves the issue.

Proxy Settings - If your VM uses a proxy to access the internet, ensure that the proxy settings are correct and that the proxy is not blocking access to the Purview portal.

Browser Cache and Extensions - Clear your browser cache or try accessing the portal using an incognito/private browsing window. Also, ensure that no browser extensions are interfering with the connection.

Check Logs - Review any available logs from the Azure Firewall, NSG, or the VM to identify potential issues or blocked requests.
