Troubleshooting Argocd: How to Fix “No Session Information” Error
If you’ve been using Argo CD for a while, you may have come across the “No session information” error. This error can occur when you’re trying to access the Argo CD web UI, and it can be frustrating since it prevents you from doing anything within the application. If you are experiencing this error, don’t worry, you are not alone. In this article, we will discuss what causes this error and how to fix it.
What Causes the “No Session Information” Error?
The “No Session Information” error usually occurs due to an expired session. Argo CD uses sessions to authenticate its users and protect sensitive data. If a session expires, Argo CD won’t know who you are or what you’re authorized to access, and as a result, you’ll see the “No Session Information” error.
Another reason why this error occurs is that the Argo CD server might be down. In this case, there won’t be any active sessions, and you’ll get the same “No Session Information” error.
How to Fix the “No Session Information” Error
If you’re experiencing the “No Session Information” error, don’t worry, there are a few solutions that you can try:
1. Clear Browser Cache and Cookies
The first and easiest solution to try is to clear your browser cache and cookies. Sometimes, cached data or cookies may interfere with your session and cause the “No Session Information” error. To clear your cache and cookies, go to your browser’s settings and search for “Clear browsing data.” From there, select the option to clear cache and cookies, and then try to access your Argo CD application again.
2. Restart Argo CD Server
Another solution that you can try is to restart the Argo CD server. This will help ensure that any active sessions are ended and new ones can be created. Restarting the server can be done by issuing the command to restart the Argo CD server.
3. Check for Certificate Issues
Argo CD uses self-signed certificates for authentication by default. If you’re using a web browser that doesn’t trust self-signed certificates, you may see the “No Session Information” error. To fix this, you can either install the certificate or add an exception in your browser.
Conclusion
The “No Session Information” error in Argo CD can be frustrating, but thankfully, it can be fixed. Start by clearing your browser cache and cookies, and if that doesn’t work, try restarting the Argo CD server. If certificate issues are the problem, try installing the certificate or adding an exception in your browser. By following these steps, you’ll be able to troubleshoot the “No Session Information” error and have your Argo CD application running smoothly again.
