TLS 1.0 and 1.1 retirement

For the last four months OS has been working closely with our customers to support their successful migration to the industry recognised TLS1.2 security protocol standards which helps keep our customers data secure. In adherence with industry practice and our cloud service provider, from 24 October 2018, OS APIs will no longer accept calls using TLS 1 or 1.1. Our support pages provide advice and guidance for you. Thank you
