This Error is usually related to TLS 1.0 connection protocol.
If you or your security team has disabled TLS 1.0, some SQL versions still use this protocol.

1. Enable TLS 1.0 for installation (you can disable TLS 1.0 once again after installation completes)
2. If help is needed to turn it on, you can use IISCrypto to enable: https://www.nartac.com/Products/IISCrypto
