The video shows the older settings. Use the values above.
Power on your display and navigate: Menu > Network > Server Network Settings > Connect to server
Enter Server Address: 7007.me
At the prompt "Enter the URL or IP address of your server.": type 7007 with the number keys on the remote; you only need the on-screen keyboard for ".me". Skip the ".com" and "www." shortcut keys.
Set "TLS" to "Use" (on older models it is called "SSL") and "Port" to 443
Select "Save"
After you save, the screen shows https://7007.me - that is correct (it adds https:// itself when TLS is on).
Set "MagicInfo mode" to Premium (if it can be changed - on some models it is fixed and greyed out)
To check the connection, look at the display itself. Opening the address in a web browser on your computer does not prove the display can connect.
A few very old display models cannot connect securely. If your display does not connect, contact support.
On OH55A-S displays the remote screen view may need different settings. Contact support if it does not work.
Only if support tells you to (very old firmware, or remote screen view on OH55A-S displays): use the server address msm.magicinfo.pro, set "SSL" to "Don't use" and "Port" to 80.
Once previous step is done, you have to create device approval request.
Open your license page and press "Add display" button
To find the serial number and model of your display: Menu > Support > Contact Samsung > Product Information (it also has a QR code button).
Enter your display IP address
Navigate: Menu > Network > Network Status > IP Settings
