On October 18, 2021 Progress will be removing support for TLS 1.0 and 1.1 protocols. Progress is discontinuing the support for these protocols to ensure Progress Web Services are using industry standard secure protocols. TLS 1.0 and 1.1 protocols were formally deprecated by the IETF (Internet Engineering Task Force) in June, 2020 (RFC 8996). Progress is taking the above actions to ensure our entire technology stack is more secure.
