I consider this a trap because it resets Firefox to again accept the older, less secure TLS versions (1.0 and 1.1). Do you want the default settings to be restored?" along with the blue "Restore default settings" button. Specifically, the note that "It looks like your network security settings might be causing this. įinally, the bottom of the message is a trap.

And, annoyingly, the message does not say what unsupported version it encountered. There are three problems, however, with this Firefox error message.įor one thing, TLS 1.0 and 1.1, which the website is using, is indeed supported by Firefox-its just that a particular instance of the browser was configured not to use them. The security protocol it refers to is TLS. Error code: SSL_ERROR_UNSUPPORTED_VERSION Peer using unsupported version of security protocol. An error occurred during a connection to. The error message from Firefox 54 when a website does not support TLS 1.2 and it only supports TLS 1.2įor the benefit of search engines, the error reads Secure Connection Failed. Last time, I discussed tweaking Firefox so that it only supports TLS version 1.2 and not the older versions (1.0 and 1.1) of the protocol.īut that begs the question: What happens when a security-reinforced copy of Firefox encounters a website that does not support TLS 1.2? The answer is shown below. There are multiple versions of the TLS protocol, and the most recent version, 1.2, is the most secure. If you are using Safari version 7 or greater, TLS 1.1 and TLS 1.2 are automatically enabled.TLS is the protocol invoked under the covers when viewing secure websites (those loaded with HTTPS rather than HTTP). There are no options for enabling SSL protocols.

If you are running an older browser, you need to enable the browser’s TLS 1.1 and/or TLS 1.2 protocols to help with page viewing.įor security, it is always recommended to upgrade your operating system and browser to be inline with industry standards.įor instructions on how to enable these protocols in your older browsers, check the list below: How to enable TLS protocols on older browsers This is especially true for supporters who may still be using Desktop Internet Explorer versions 8, 9, or 10.

Some of your supporters might still be running older operating systems and browsers, and if they have not enabled TLS v1.1 and TLS v1.2 under their browser’s settings screen, then Engaging Networks pages will fail to load for them. If you are an organisation that has third party providers connecting to Engaging Networks, through APIs, you should confirm that these providers are TLS 1.1 and TLS 1.2 ready. Modern browsers now use the latter methods for processing.Īs a day to day user of Engaging Networks, using a modern browser, and (if relevant) as an organisation processing payments on behalf of your supporters, you will see no change after the 1 June 2018 update. TLS 1.0 has already been superseded by TLS 1.1 and TLS 1.2. Please note that no downtime will be required for the update. As of 30 June 2018, the Payment Card Industry (PCI) requires all data processors to withdraw support for the encryption method Transport Layer Security (TLS) version 1.0, as it is no longer regarded as strong ‘cryptography.’Įngaging Networks will disable TLS 1.0 on 1st June 2018 at 1 pm EDT / 6pm BST.

The encryption protocol deploys whenever a web browser or application transmits data over a network. TLS, short for Transport Layer Security, is an encryption protocol that protects data in transit from one server to another.
