Downtime Viewer Error

Downtime viewer returns "400: Bad Request" error

Possible root cause: The length of the URL is too long, exceeding the default value.

Resolution: Increase the value of the server.max-http-header-size property to 20kb (server.max-http-header-size=20000) in the prod.properties file. The maximum size allowed is 48kb.

Depending on your installation, access the prod.properties file in the following folder:
  • Enterprise installation: <Install Directory>/PlantApplicationsDocker/plantapps-web-docker/mnt/configfiles/common-service/prod/<service-version>/common-service-prod.properties
  • Standard installation: <Install Directory>\config-repo\common-service\prod\<service-version>\common-service-prod.properties

Ensure this line is not marked as a comment and restart the service to apply the change.
