By default the DTR services are exposed using HTTPS, to ensure all communications between clients and DTR is encrypted. Since DTR replicas use self-signed certificates for this, when a client accesses DTR, their browsers won’t trust this certificate, so the browser displays a warning message.
You can configure DTR to use your own certificates, so that it is automatically trusted by your users’ browser and client tools.
To configure DTR to use your own certificates and keys, go to the DTR web UI, navigate to the Settings page, and scroll down to the Domain section.
Set the DTR domain name and upload the certificates and key:
Finally, click Save for the changes to take effect.
If you’re using certificates issued by a globally trusted certificate authority, any web browser or client tool should now trust DTR. If you’re using an internal certificate authority, you’ll need to configure your system to trust that certificate authority.
