Resolved
Between 19:49 UTC and 21:07 UTC on August 25, 2026, customers attempting to log in to CircleCI using GitHub were unable to sign in, and received an error from GitHub stating the callback URL was invalid. Customers who were already logged in were not affected. The issue has been resolved and GitHub login is functioning normally. We thank you for your patience while our team worked on implementing a fix.
