UrlsAccessibleCheck - failed

Question

Hello,

I have a problem at hosts pools in azure where UrlsAccessibleCheck failed with:

"To resolve this, you'll need to reconfigure your networking, firewall, or proxy settings to unblock the following inaccessible URLs:

gcs.prod.monitoring.core.windows.net"

When I check from the avd I got this:

Where is the mistake? I am trying to find this all day.

Thank you very much for your time and help,

Mikolas

Hi Mikoláš Kaplan,

The issue you are experiencing with the Azure Virtual Desktop (AVD) host pools failing the UrlsAccessibleCheck is likely related to network configuration, firewall settings, or proxy restrictions that are blocking access to the required URLs.

The session host doesn't pass the UrlsAccessibleCheck health check, you'll need to identify which required URL your deployment is currently blocking. Once you know which URL is blocked, identify which setting is blocking that URL and remove it.

There are two reasons why the service is blocking a required URL:

• You have an active firewall that's blocking most outbound traffic and access to the required URLs.
• Your local hosts file is blocking the required websites.

To resolve a firewall-related issue, add a rule that allows outbound connections to the TCP port 80/443 associated with the blocked URLs. UrlsAccessibleCheck
