It sounds like your browser has certain aspects of SSL disabled or can't support the higher levels. Doing the move to be PCI compliant we had to turn off TLS 1. By turning this off, we make sure people's credit card info is not sent in an outdated format.
People with Windows 7 and above might need to update their IE settings. In IE, go to Tools menu -> Internet Options -> Advanced. Scroll to the bottom i.e., to the Security section. You would see the list of SSL protocols supported by IE. Both TLS 1.1 and 1.2 need to be checked. These settings were turned off in early releases of Windows.

SSL and TLS 1.0 are no longer acceptable for PCI Compliance. To ensure the continued strength and integrity of PCI Standards for payment data protection, the PCI Council has ongoing processes for monitoring threats and vulnerabilities and for updating the standards as necessary. The National Institute of Standards and Technology (NIST) has identified the Secure Socket Layers (SSL) v3.0 and TLS 1.0 protocol (a cryptographic protocol designed to provide secure communications over a computer network) as no longer being acceptable for protection of data due to inherent weaknesses within the protocol. Because of these weaknesses, no version of SSL or TLS 1.0 meets PCI SSC’s definition of "strong cryptography," and revisions to the PCI Data Security Standard (PCI DSS) and the Payment Application Data Security Standard (PA-DSS) are necessary.
