Have you checked your hosts file to see if GitHub.com somehow became entered in it? If so, remove that and try again.
/etc/hosts
Another thing to check is what DNS server you are using. Perhaps try changing that to be assigned by DHCP.
If it already is, try manually entering it.
DHCP Servers:
8.8.8.8
1.1.1.1
Those are Google and Cloudfare respectively.

It is. The OP has (or rather, had) some kind of proxy software running locally - maybe the infamous "privoxy" software.
Honestly ,I am using proxies due to the dns pollution , (the special circumstances of my nearby network),maybe that is the problem,but if the proxy is dead, most of the website can not be connected,the problem is that most website can be visited except GitHub,so it is weird ,and It never happened before .

A fair percentage of all problems on macOS, going back many years, can be summarized as follows:
I was doing something really crazy for years. Then <insert new macOS version here> came along and broke it!
Fix this Apple!!!!!
it dose not help,even If I changed my dns server to 1.1.1.1 or 8.8.8.8 😭
btw,i am using proxies, proxy is on 127.0.0.1,but I can not find the problem ,and I have not changed anything before GitHub can not be connected
I thought 127.0.0.1 was reserved for local host or loopback? Is that really what you want to do?
yes ,proxy needs to work on 127.0.0.1::7890 as a local host service
