  • you get 302 when performing URL redirection, any ELB Health check will look for success code 200 for the health check to pass. In ALB, this can be configured under health check in the ELB console.

    To modify the health check settings of a target group using the console

    1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
    2. On the navigation pane, under LOAD BALANCING, choose Target Groups. Select the target group.
    3. On the Health checks tab, choose Edit.
    4. On the Edit target group page, modify the setting Success Codes to 302 or as needed, and then choose Save.
