Overview

When trying to log into CircleCI, the login page kicks you back to the login page after logging in with no error message.

You may experience this when signing up with an email/password account and then try logging in with your GitHub account.

As you may be aware, we have been putting efforts into identifying potential abusive use cases such as crypto-mining here at CircleCI. This is an interesting but rather challenging effort.

Solution

Browser-related Issues

From time-to-time we have noticed that browser extensions can have a knock-on effect to how CircleCI performs and this includes issues with logging in.

If you’re experiencing problems logging into CircleCI, please try using Private Browsing(Apple Safari/ Mozilla Firefox), Incognito Mode (Google Chrome) or Microsoft Edge (InPrivate) and attempt to log into CircleCI. If you’re able to log into CircleCI, these would suggest that the issue is related to a one of your extensions.

To pinpoint which extension is causing the issue, return to normal browsing mode and disable all extensions. One-by-one reintroduce each extension and attempt to sign-in to CircleCI and then sign-out again. At some point during the re-introduction of your extensions you should expect the logging in issue to appear again. The last introduced extension is the most likely reason why you’re having trouble logging in.

Networking-related Issues

Networking issues can also contribute to problems logging into CircleCI. These can range from VPN issue, to firewall issues. To troubleshoot this, we recommend creating an HAR file. This file is a JSON-formatted log that captures all the network traffic between your browser and a website (in this case CircleCI) including requests and responses. Steps on how to create this can be found here: Creating an HAR file.

The created file can either by analyzed using an HAR Analyzer tool such as the HAR Analyzer in the Google Admin Toolbox , which is what we use to or you can send it into us as a support ticket for us to look over.

Abuse Prevention Mechanisms

To prevent abuse, CircleCI is constantly implementing abuse prevention mechanisms and techniques. Please try logging in with your GitHub account the next day.
