Hey guys! Is the OTC Updater EOL'd? I'm getting an error when trying to update a stubborn device. Do you think there is a string that could be change?

Anyone with an Enterprise Support Agreement want to see if they can find out wassssup if we can't figure anything out here?

Windows Update service migrated to TLS 1.2 but OTC tool is built against .NET 4.0 that does not support TLS 1.2.
Support for Windows Phone 8.1 and Windows 10 Mobile has ended and that’s why also OTC is out of support and Microsoft is not making updates to that.
However, users can still get the existing OTC tool to work by adding 8 required entries:

    I have recompiled the binary (otcupdater.exe) with .net 4.7 which should support tls 1.2 and newer
