Hi, @zheng980423. If you cannot ping 35.201.69.186 then there is some issue with your local networking.
If you are in China or Russia? They are both known to sometimes block access to IP addresses that Netlify uses:
This is true both for API IP addresses like 35.201.69.186 and for our CDN nodes which serve deployed sites’ files.
Your local networking issue is the root cause of the login not working. You must resolve that networking issue for the login to succeed.
If there are other questions about this, please let us know.
