ALB + Route 53 Setup - 400 Bad Request When Accessing Domain

[ooii8929]

Environment Details:

Infrastructure: AWS EC2
Container: IQ Container
Load Balancer: Application Load Balancer (ALB)
DNS: Route 53

Hey Community,
I'm running into a bit of a tricky situation with my ManageIQ setup and could use some expert advice. 🤔

So here's the deal: I've got ManageIQ containerized and running smoothly on an AWS EC2 instance. No problems accessing it directly via IP address - everything works great! 👍

But now I'm trying to level up my setup by:

Putting an Application Load Balancer (ALB) in front of my instance
Configuring Route 53 to point my domain (xxx.com) to the ALB
The catch? When I try accessing via my domain, I'm getting a 400 Bad Request error. 😫

I've already checked the Apache access logs

my ip - - “GET / HTTP/1.0” 400 362

I suspect the issue lies in the Apache-ManageIQ integration, potentially involving TLS configuration mismatch?

Any insights or troubleshooting steps would be super appreciated! 🙏

Cheers

We store a lot of data in the session, so you'll need to ensure the load balancer is using sticky sessions.

You may be able to pick up some tricks from https://www.manageiq.org/docs/reference/latest/high_availability_guide/

Maybe @bdunne or @Fryguy have more ideas?
