SSLVersionMin Policy returns to Chrome 66

Chrome 66, releasing to stable this week, again supports the SSLVersionMin policy that enables administrators to control the minimum version of TLS that Chrome is willing to negotiate with a server.

If this policy is in effect and configured to permit, say, only TLS/1.2+ connections, attempting to connect to a site that only supports TLS/1.0 will result in an error page with the status code ERR_SSL_VERSION_OR_CIPHER_MISMATCH.

This policy existed until Chrome 52 and was brought back for Chrome 66 and later. It is therefore possible that your administrators configured it long ago, forgot about the setting, and will be impacted again with Chrome 66’s rollout.
