I'm using the C# SDK to connect to Azure IoTHub in testing. I'm using the C#SDK symmetric keys and DPS. I've modified DeviceReconnectionSample to work with SymmetricKeySample/ProvisioningDeviceClientSample. Sometimes it works, and sometimes I get this. Note that the connection to DPS works the first time, so I have the correct certificate, and then fails on retry.

I appreciate it if you can share the modifications made you have made to the DeviceReconnectSample class to help us better understand the potential cause of this issue. Please let us know if you have made any changes to the reconnect logic in the code. Also, it looks like you are trying to use certificates through the sample. I would like to check with you and see if you have reviewed the article Provision an X.509 certificate simulated device. This provides the steps needed to provision a device using certificates. Kindly review this and see if this addresses your testing needs without having to modify the code.
