The command run is brew update
and then an error is reported
SSLRead() return error 9086
It seems that all browsers cannot browse https now.
It will show that the connection is not secure.
I encountered some problems before
Used command option R P
and command option shift control power to reset.
Update
You can use brew normally if you have http_proxy and https_proxy proxies in your unit.
But I didn’t set the variable when I went home, and still got an error.
I changed ali’s dns to 114dns and still can’t solve it.

On Mac, use the terminal command line tool: brew, whether it is installing or updating the tool. If an error occurs, you can consider the following two methods:
1. The simplest way: directly open the preferences, open: Network --> ;dns->Change to Baidu or Alibaba 180.76.76.76, or: 223.5.5.5;
2. If you still can’t solve the problem, you can try using a VPN. If you don’t want to spend money or register, you can download FreeVPN++ from the Apple Store , I have been using it, very conscientious;
If you encounter some websites, because they are not HTTPS connections, report them as unsafe or the like. If you are sure that there is no problem with this website, you have visited it before, or it is a well-known website, you don’t need to pay attention to it. Tip, just choose to ignore it.
For example: 12306.cn, including PHP Chinese website php.cn, because it is not HTTPS, it will also be falsely reported, just ignore it.
