Oauth error: timestamp_refused

Today, a large number of server errors are reported. Most users cannot log on, but a small part of the server can log on, which is strange.

Check the log, debug the code, and find that the problem occurs during oauth authentication, and report timestamp_refused.

Google asked the experts, and the problem was located at the server time.

Execute date, and it is 5 minutes faster than other servers

[Root @ localhost ~] # Date

After synchronization, the problem is solved.

[Root @ localhost ~] # Ntpdate time.windows.com
