I agree if you use ADDS also on the same Server., please refer MS article for AD LDS setup.

I went through this article and decided to use third party SSL instead installing CA on DC.
I can test connect on port 636 without any errors but can not on port 50001

Do you have AD DS service also running on same server?

    Please check Windows Firewall on same server if If port is blocked or temporary Turn off the Firewall using below command. If you have third party AV firewalll you also need disable it.
    Netsh Advfirewall set allprofile state off.
