Access is denied for RPC over HTTPS

Hi,

I'm getting an error when trying to connect to M-Files Desktop 23.8 (newest version) via RPC over HTTPS.

I am having no issues with M.-Files web, but desktop doesn't work. When configuring login in mfiles desktop settings - testing connection and Test connnection to document vault both work. But when trying to log in - I get an error below.

I already went through M-Files official troubleshoot guide for RPC over HTTPS and everything is set up correctly.
