Hello Maxim,
uh, nope I cannot connect using SSMS. Same error, so I guess this is a OS related issue I need to adjust?

The current RDM version is the latest published till today.

Thank you.

Hello

What's your client OS? TLS 1.3 isn't supported and/or enabled by default on all versions of Windows.

Hello Riichard,

I have W11 installed.
I already found that TLS can be adjusted with specific registry keys. TLS seems not to be enabled by default. I guess RDM TLS compatibility also depends on the OS settings and is not dedicated to RDM config only.
Cheers,
Philipp

Hello

Right on - if you enable TLS 1.3 in the schannel configuration, and can connect with SSMS but not RDM, please let us know.

Note that older Windows versions either don't support, or don't fully support, TLS 1.3 so if backward compatibility is a requirement you might want to enable this with care.

Kind regards,
