Is there some type of limit to how many requests can come from a single IP?
Last week I tried to have my students create GitHub accounts, and a few were able. But most got a “something went wrong” message next to the username field and a 419 error in the browser console. The next group signed up after a quiz, so they were more spread out and didn’t have any problems creating accounts.
Today we’re cloning and a handful of students kept getting authentication errors. Usernames and passwords were correct, and if they waited a few minutes then they would be able to get in.
