Managing domain

The IoT Hub allows registering your custom domain. When you register your domain, IoT Hub will automatically request SSL certificate from Let’s Encrypt for it and will manage further certificate renewals. After domain registration, you will be able to access IoT Hub Web UI via your domain name using secure HTTPS connection. Like Web UI all other IoT Hub services such as MQTT/HTTP/CoAP transports or HTTP integrations will be accessible via your custom domain name.

Domain registration


In order to use your own domain name to access IoT Hub you must register it first. Follow the next steps to do that:

  • Step 1. Expand White Labeling menu section in the left pane and click on the Domain menu.
  • Step 2. On the Domain page click Register domain button.
  • Step 3. Enter your domain name in the Register domain dialog and click Register button.
  • Step 4. Follow the instructions form the Domain provisioning dialog. At this step you will be asked to add CNAME record to the database of your DNS service Provider. See How to Create a CNAME Record For Your Domain for details.
  • Step 5. After registering CNAME record, click I’ve added CNAME records button. Domain verification and certificate provisioning will start at this time. Be patient, this process can take a while.
  • Step 6. If all went well, dialog will be closed, and you will see your domain name on the Domain page. Now you can use your domain name to access IoT Hub Web UI and services.
  • Step 7. In case of any issues during domain provisioning you will see the dialog prompt with error details. In this case you should try to correct the issue (ex. correct invalid entered CNAME record) otherwise you can contact support.

How to Create a CNAME Record For Your Domain

The procedure of adding CNAME record to DNS database depending on your DNS service Provider. Below is the list of instructions for some popular DNS providers:

If you don’t find your DNS provider in the list provided try to get this information on the providers website or by contacting your provider support.

Troubleshooting

Firs of all you need to check if you have added CNAME to your domain correctly:

Use Google Admin Toolbox or “dig” command if your OS system is Linux:

1

dig YOUR_DOMAIN_NAME any

The “dig” command in Linux is used to gather DNS information. It stands for Domain Information Groper, and it collects data about Domain Name Servers. The “dig” command is helpful for diagnosing DNS problems, but is also used to display DNS information.

The output of “dig” command could vary duy to your domain setup. For example:

1

3
4
