Modern Web Browsers Cannot Access Older CyberData Products.

Modern Web Browsers Cannot Access Older CyberData Products.

In late February of 2022 Google made a change to their Chrome Browser (98.0.4758.102), that also affects other Chromium Based-browsers, which prevents connection to any web server that allows connections to versions of TLS older than v1.2. Even though the web server may currently be running TLS 1.2, if the web server also permits downward compatibility to older TLS, then Chrome and Chromium-based browsers (Edge, Opera, Vivaldi, and others) will no longer permit connection.

Some of the older firmware releases for our devices prior to December 2019 optionally support TLS versions 1.1 and 1.0 which will prevent web access through the web browsers mentioned above. In most cases, upgrading to the latest available firmware release will resolve the TLS issue. If a TLS 1.2 firmware upgrade is not available for your product, your device may still be accessed with an older browser such as Internet Explorer as well as older versions of Chrome and Mozilla Firefox.

Firefox, not being a Chromium-based Browser, can be made to allow 
connecting to any web server that allows connections to versions of TLS earlier than 1.2 but this requires a change to the browser's security settings.

Type about:config into the browser's address bar and hit Enter. You should see a screen that looks similar to this one. Or you may need to select "Show All" to be able to see it. Scroll down to "security.tls.version.min" and change the value from 3 to 1. Then restart the browser. This should enable you to access the Web Interface of any of your CyberData products.




Note that if a newer CyberData firmware version that permits browser connection without these modifications is released, you will temporarily need to use the modified browsers or Internet Explorer to access your device while uploading and installing the newer firmware.
