CHROME REMOVES TLS 1.0 AND TLS 1.1
Google has now removed support for the TLS 1.0 and TLS 1.1 ciphers. These two ciphers are considered insecure. Websites that load via HTTPS and use these two ciphers will be blocked in Chrome by default and users will see an error message like the one below.
Chrome and all other major browsers have announced plans to dump TLS 1.0 and TLS 1.1 since 2018, so most websites have already updated their HTTPS certificates. However, there's always sites that lag behind. Users should expect some of these messages to pop up once in a while as they try to access older or unmaintained websites.
Just like many recent Chrome features, this was actually scheduled to go into effect earlier this year, in Chrome 81, but Google delayed its rollout because of the coronavirus pandemic. Google believed this would have resulted in extra work for webmasters and system administrators who were already busy dealing with new work-from-home schedules.
