    *Edit to remove extra characters from registry key paths

    Hi Neil,

    This will be the result of either or both TLS 1.0 and SSLv3 having been disabled. Both the client and server TLS 1.0 and SSLv3 need to be enabled for the web service to be able to talk to the base monitor.

    These are all of the registry keys and their values for enabling both the client and server portions of SSL 3.0 and TLS 1.0:

    SSL 3.0: 

    We are aware that from a security point of view, we should no longer use TLS v1.0 and SSLv3 and instead we should use TLS 1.2. An internal issue has been created for this to be considered for a future version.

    Kind regards,
