UpdatesClient in C# reporting no such host is known after 4 retries. about iot-hub-device-update HOT 6 CLOSED

Yes, I am aware of how to create the credentials and I can execute the raw calls in the RESTful API. I have it prototyped in Postman, but here is a segment of my C# code: var credentials = new ClientSecretCredential(appConfig.DpsOptions.TenantId, clientId, clientSecret); updatesClient = new UpdatesClient(iotHubInstanceConfig.AduAccount, iotHubInstanceConfig.AduInstance, credentials); devicesClient = new DevicesClient(iotHubInstanceConfig.AduAccount, iotHubInstanceConfig.AduInstance, credentials); deploymentsClient = new DeploymentsClient(iotHubInstanceConfig.AduAccount, iotHubInstanceConfig.AduInstance, credentials); The iotHubInstanceConfig is a configuration element that is both injected by DI and is managed by region changes. I have verified that the values that I am passing are correct and I can demonstrate thos same values work in a Postman call. The Url for my adu instance API endpoint is https://aeddevtest.api.adu.microsoft.com/deviceupdate/vyper/v2/updates/providers Thanks!

Okay, sometimes it takes another set of eyes! My Postman prototype used a URL: let aduHost = pm.environment.get("aduAccount"); let baseUrl = https:// + aduHost + ".api.adu.microsoft.com"; Your class model uses just the host name. Thanks! You can close this issue.

Sure, we need it to test devices for Certification! So far it's going pretty well. About the only thing major I had to do was to implement chunked Blob storage upload of the swu file for the update because they can be quite large. So glad you have a class model so I didn't have to implement a RESTful client!
