Yeah, the error indicates that Inquisit can't establish an SSL connection to the server -- Inquisit uses the operating system's standard SSL library for that, so the error doesn't directly originate in Inquisit, but at the level of the underlying operating system. Reasons could be:
- An outdated system SSL library, installing all available outstanding system updates should fix that.
- A misconfiguration in the operating system's SSL settings, specifically it may be that TLS has been disabled, although this is rather unlikely.
- Some other application, firewall or proxy in the network is messing with or preventing the SSL connection.
