Hi -

 

Is anyone seeing the dreaded DSC Extension error upon provisioning new pools today?  I have one pool working fine - and have run into this three times in a row with a brand new pool deployment attempt.  Error on last step:

 

{"code":"DeploymentFailed","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-debug for usage details.","details":[{"code":"Conflict","message":"{\r\n \"status\": \"Failed\",\r\n \"error\": {\r\n \"code\": \"ResourceDeploymentFailure\",\r\n \"message\": \"The resource operation completed with terminal provisioning state 'Failed'.\",\r\n \"details\": [\r\n {\r\n \"code\": \"VMExtensionProvisioningError\",\r\n \"message\": \"VM has reported a failure when processing extension 'dscextension'. Error message: \\\"The DSC Extension failed to execute: Error downloading https://catalogartifact.azureedge.net/publicartifacts/rds.wvd-provision-host-pool-8f893fe9-5016-43c6... after 29 attempts: Unable to connect to the remote server.\\nMore information about the failure can be found in the logs located under 'C:\\\\WindowsAzure\\\\Logs\\\\Plugins\\\\Microsoft.Powershell.DSC\\\\2.77.0.0' on the VM.\\\".\"\r\n }\r\n ]\r\n }\r\n}"}]}

Any users reporting this again?  I'm kind of back to square one.  Last step - DSC Extension piece - provisioning attempts to download a zip file from catalogartifacts.azureedge.net 29 times and then finally fails.

 

The sad thing is I can literally take the full URL path to the zip that's reported in the error, open a new browser tab, enter the URL and display the contents of the zip.....what is going on with this?

One more comment here.  I just tried a new pool, in a different subscription (bound to a different geographical region).

 

This pool succeeded on first attempt (UK South).  I immediately tried another pool in a subscription that is bound to US East - it fails with the DSCExtension (all my other attempts in the last two days have been in that US East sub....).

@jaycrumpgp : Are you using a custom image or just a default image from the Azure Gallery? We've had customers report intermittent failures, but not something as consistent as what you're shared.

@christianmontoya 

Hey Christian - sorry, I've been on different project work all week.

 

I finally figured this one out.....it was the vnet and subnet I was trying to bind to the East US WVD pool.  I had no default route set, so..no internet...so...the session host couldn't ever download that zip file from the azureedge.net URL that it kept failing on.

 

Live and learn - thanks for following up!
