Github cannot be accessed (resolved) The hosts file cannot be modified (resolved) The webpage with the URL https___github.com_ may be temporarily unavailable, or it may have been permanently moved to a new URL.

I can’t log in to Github recently, and I have found a lot of solutions and finally found it!

I turn off this plug-in of chrome, and then I can enter again (if it doesn’t work, turn off other plug-ins and try).

If you can’t solve the problem by closing the plug-in, you can try the following methods.
Enter this website, find the ip address, and remember him

https://fastly.net.ipaddress.com/github.global.ssl.fastly.net

Then enter this website:

https://github.com.ipaddress.com/

Find the ip address, remember it,
and then open the c drive to find the hosts in this path and

add the ip you just remembered. It's

almost solved.
If the hosts can't
be modified, then set the following
right-click hosts and select Properties --> Security --> Edit, tick the full control of the group or user name at the beginning of ALL and Users, and then confirm it!
