Description
Numerous service providers are in the process of revising their Transport Layer Security (TLS) protocols by systematically discontinuing support for TLS 1.0 and 1.1. Consequently, all clientele will be mandated to establish connections through TLS 1.2 or superior iterations.
Utilization of a legacy version of the Analytics firmware will result in the occurrence of the mentioned error, as this version lacks the implementation of TLS 1.2 or subsequent iterations.
Resolution
To fix the current issue, you will need to upgrade the firmware of the Analytics. To perform this, use the following steps:
1. Navigate to ip_of_the_Analytics/appliance page | System | Diagnostics, check the Technical Support Report (TSR) option and click on the Export button.
NOTE: It can take few minutes to generate the TSR report, so please allow this operation to complete and if a timeout occurs then you will be required to login back in and restart the operation.
2. Verify on the TSR your current firmware version and use the following path to find the next versions you will need to download and use to upgrade your firmware.
2.5.2515 | 2.5.2517 | 2.5.2518 | 2.5.2519 | 2.5.0.3-2520 | 2.5.0.3-Hotfix-1 | 2.5.0.3-Hotfix-2 | 2.5.0.3-Hotfix-3 | 2.5.2
NOTE: Direct upgrade to Analytics 2.5.2 is not supported. To upgrade to Analytics 2.5.2, proceed by following the KB article attached below:
