What Does ‘Unsupported Protocol’ Mean?

We place the highest importance on the security of our customers’ data.

In order to maintain the highest standard and protect your data from known security risks, Dext has stopped supporting the outdated security protocol TLS 1.1 and will only support the more secure TLS 1.2 protocol.

These protocols run as part of your internet browser and, if it does not use TLS 1.2, you’ll receive the following message when you try to access the Dext web application:

Unsupported Protocol –ERR_SSL_VERSION_OR_CIPHER_MISMATCH 

This means you have an outdated browser that does not use TLS 1.2. 

To access Dext you must have a more recent version of your internet browser. 

Below is a list of unsupported browser versions. Please click the Update Link to be taken to that browser’s download site where you can update your browser. Click here if you don’t know which internet browser you use.
