In order to meet PCI Data Security Standard, dxFeed migrated its services to later versions of TLS (Transport Layer Security protocol). TLS 1.0 will be disabled for dxFeed services on June 30, 2018. More secure encryption protocols are implemented: TLS 1.1, TLS 1.2 and TLS 1.3 are already available for connection.
TLS 1.0 will be disabled on June 30, 2018. Please check that you use TLS 1.1, TLS 1.2 or TLS 1.3 by this date.
