Outage Details

For customers encountering challenges while accessing specific sites with decryption enabled and upon receiving "decrypt-unsupport-param" logs, particularly when using Google Chrome browser version 124 and higher, we suggest trying the following steps: Issue Identification: The observed difficulties may arise from Kyber Support integrated by Chrome for the TLS 1.3 version. Chrome Flags Configuration: Please review the configuration settings in Chrome Flags. This can be done by navigating to "chrome://flags/#enable-tls13-kyber" and examining the setup. Disabling the Option: We encourage you to consider disabling the Kyber Support option and then relaunching the browser to assess if it resolves the issue. If you continue to experience any difficulties, please open a support case, sincerely appreciate your patience as we diligently work to resolve this matter.
