How do we change the TLS version of Azure IoT Hub which is already created and deployed?


I see that we can enable TLS version only during IoT Hub creation in Azure portal.How do we change this version POST creation? we have already deployed in PRODUCTION and now we need to change it.

Solution

  • Unfortunately, you can't. There is no option in the portal for this, and it can't be achieved through ARM either. Trying it with ARM will result in the following error:

    MinTlsVersion cannot be set when IotHub is in Active state
    

    The documentation confirms that this field is read-only and can't be changed.
