Error: Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in advanced settings Apr 20, 2023
The error "Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in advanced settings" typically occurs when a website or service is configured to only allow connections using the Transport Layer Security (TLS) protocol version 1.0, 1.1 or 1.2, but your browser or client is not configured to use those versions. Here are the steps to enable TLS 1.0, 1.1, and 1.2 in different web browsers:
- Internet Explorer: a. Open Internet Explorer. b. Click the gear icon in the upper-right corner of the browser, then select "Internet Options." c. Click the "Advanced" tab. d. Scroll down to the "Security" section. e. Check the boxes for "Use TLS 1.0", "Use TLS 1.1", and "Use TLS 1.2" f. Click "Apply" and "OK" g. Close Internet Explorer and restart it for the changes to take effect
- Google Chrome: a. Click the three dots in the upper-right corner of the browser. b. Select "Settings" c. Scroll down and click "Advanced" d. Scroll down to "Security" e. Click "Use TLS 1.3" (by default) and select "Use TLS 1.0" , "Use TLS 1.1" and "Use TLS 1.2" f. Close Chrome and restart it for the changes to take effect.
- Mozilla Firefox: a. Type "about:config" in the address bar and press enter. b. Click "I accept the risk!" to continue. c. In the search bar, type "tls" d. Double-click on "security.tls.version.max" and set the value to 3 e. Double-click on "security.tls.version.min" and set the value to 0 f. Restart Firefox for the changes to take effect.
- For Safari on MacOS, please check in the settings of your operating system if the appropriate version of the protocol is enabled.
Note: Please keep in mind that enabling older versions of
the TLS protocol may reduce security as newer versions have more secure ciphers
and encryption. After enabling the older version, it's highly recommended to
check the security of your website using some online security scanner such as
Qualys SSL labs and make sure your site is secure and no vulnerabilities are
present. As browser version are updated the enabling/disabling section may
change in future
