我剛剛查fx release note，發現有一個更新修正：

原來的：
We have disabled TLS 1.0 and TLS 1.1 to improve your website connections. Sites that don't support TLS version 1.2 will now show an error page.

修正：
We reverted the change for an undetermined amount of time to better enable access to critical government sites sharing COVID19 information.

不過既然舊版的TLS有漏洞，我想還是請站長升級到1.3吧。
