Transport Layer Security (TLS) is a critical security protocol used to protect web traffic. It provides confidentiality and integrity of data in transit between clients and servers exchanging information. Klarna is disabling support for older versions of TLS, below 1.2 across public facing endpoints, beginning April 2st, 2024. If you connect to Klarna after this the older protocols are disabled and you will receive connection error messages.
No impact is expected to clients using Transport Layer Security 1.2 for their connections.
