Type your custom domain in the "LetsEncrypt" field as seen below. This can be found under the "Customize" settings of your Team page.

If you choose to use other SSL certificates, follow these steps.

    • Team admins will go to the "Team" page on your web app. If you are on a Pro account, you will go to "Account" settings.
    • Click "Customize."
    • Upload your Certificate, Private Key, and Certificate Chain.
