Hello,

Possibly linked to an old AS version. You need to download the upgrades from the website and install them from local “Browse..”.

See [SSL / TLS encryption required for access to Technology Guarding Server and Automation Studio Upgrades](https://community.br-automation.com/t/ssl-tls-encryption-required-for-access-to-technology-guarding-server-and-automation-studio-upgrades/3049) for more information.
