Periodic authentication failure with GitHub repositories

Last update
  1. resolvedSep 3 · 16:41 UTC

    Semaphore is currently operating normally, which is why we’re marking this incident as resolved. GitHub confirmed that the behavior affecting unauthenticated Git operations is the result of an intentional change on their end rather than a bug. You can read their latest statement here: https://github.com/orgs/community/discussions/206581#discussioncomment-18269083 For builds affected by this behavior, the previously shared workaround remains available. Configure Git to use HTTP/1.1 before running the affected Git operation: git config --global http.version HTTP/1.1 We will add this instruction and further context to our documentation. Any additional guidance from Semaphore will be shared through in-app notifications. For further assistance, contact our support team at support@semaphore.io.
