Google is planning to deprecate TLS 1.0 and TLS 1.1, targeting removal in Chrome 81 (early 2020).
During the deprecation period, sites using those protocols will show a warning in DevTools. After the deprecation period, in 2020, they will fail to connect if they have not upgraded to TLS 1.2 by then.
