Our team will be disabling support for TLS 1.0 and 1.1 on all Stitch services on 2021-04-22.
TLS 1.0 and 1.1 are obsolete versions of Transport Layer Security (TLS) that are no longer considered secure. To keep Stitch services in line with Internet best practices, all services will be updated to only support TLS versions 1.2 and higher. After 2021-04-22, any services using TLS 1.0 or 1.1 will no longer be able to connect to any Stitch services.
All major operating systems and browsers currently support TLS 1.2 or higher, and, for users on current software, there should be minimal to no effect. Customers on legacy browsers and operating systems are encouraged to take action now to avoid any disruption to Stitch service.
