- This is now resolved, with the help of MS support. I'll just copy and paste the case summary here, since it captures the issue pretty well.
Symptom: Need help in fixing session host deployment failure when adding a new session host in host pool.
Resolution: We helped you in fixing the session host deployment failure by asking you to use a NAT Gateway to provide a fixed public IP address for your session hosts rather than a load balancer.
This allows you to replace your Load Balancer and on a per subnet level, allows all outbound connections to use specified static public IP address(es).

David Schrag Hi David, we are working on solutions to make an image easier to customize and apply to existing host pools. Meanwhile, both options you listed are supported and should work without issues. There are many reasons why the VM isn't able to access the URL you provided, including proxy or firewall settings within your Azure subscription or Windows image. I won't try to troubleshoot this issue over a forum but please try to exclude as many on your end that could impact network for Windows to download the required package.
Microsoft support should be able to help you troubleshoot, if you can share your CSS ticket through a private message I can look if there's anything I can help with.
- Thanks for the reply. I am supposed to have another troubleshooting call with support in two days. I will PM you the ticket number.
