- In Server Manager → Configuration → under SSL Certificate select Custom Certificate.
- Click browse, Select your .pfx certificate file and then click OK.
- Provide the Password in pop-up window
- Save & Restart Server, so that Output Messenger will use your SSL certificate & encrypt all communication messages.
