Troubleshooting Production
Symptoms
- "This site can’t be reached" in Chrome
- Requests timing out
Diagnose
On a unix command line, run
dig <your CiviForm domain>
. (Note: Remove the protocol -- http
or https
-- from the front of your domain before running the command.) There should be a CNAME
entry that points to an AWS load balancer e.g. seattle-civiform-lb-2038295446.us-west-1.elb.amazonaws.com.
Confirm that the
CNAME
record matches the public domain for your AWS application load balancer by visiting the AWS console EC2 > Load Balancing > Load Balancers and finding the load balancer for your prod deployment.Resolution
If the
CNAME
entry is missing or does not match the DNS name you find in AWS, add or update a CNAME
entry in your domain registrar with the application load balancer's DNS name.Symptoms

- Requests timing out
Diagnose
View the ECS cluster for your prod deployment in AWS by going to ECS > Clusters and clicking the cluster for your production deployment. There should be at least one healthy task. If all tasks are unhealthy or unknown the server is unable to start.
If no tasks are healthy, view the server logs (see Server errors below). Look for stack traces and error messages.
Resolution
If you have just deployed, revert your CiviForm version number to the previous version you deployed and re-deploy.
Contact the CiviForm maintainers and include any errors you found in the server logs.
Symptoms
Server returns 400 or 500 level errors or pages with short, plaintext messages stating an error message.

Server error example
Resolution
If you have deployed recently, consider reverting your CiviForm version number to the previous version you deployed and re-deploying.
Investigate the server logs. Report any errors you find along with complete stack traces to the CiviForm maintainers. To view the server logs in the AWS console go to CloudWatch > Logs > Log groups, select the log group for your production deployment and view the combined log stream.
Symptoms
Users are unable to log in.
Resolution
Check with maintainers of the admin and applicant auth systems if there have been recent changes. Check the release notes for your CiviForm version to see if it mentions auth changes. If errors are occuring after the user successfully authenticates with the identity backend and redirects back to CiviForm there is likely a server error involved. Check server logs for errors.
Contact CiviForm maintainers with details of the investigation.
