Nodejs AWS EC2 404 Not Found

Question

Hey there,

Nodejs app deployed on AWS EC2, other software/ services include Apache, configured ACM, and Cloudfront. DNS is a 3rd party service.

Throws following error:
_____________
```
Not Found
-------------------
The requested URL was not found on this server.

Apache/2.4.41 (Ubuntu) Server at ec2-XXX.eu-central-1.compute.amazonaws.com Port 80
```
_____________

What could be the reason?

Thanks for your help :)

Answer

The error message is clearly coming from Apache indicating the requested object is not found. The apache logs would be a good place to start for troubleshooting. However, if this behaviour is new since configuring CloudFront, it might be due to the host header value: CloudFront will set the Host header to the origin DNS domain name when making requests to it, unless you configure it to forward the Host header: https://aws.amazon.com/premiumsupport/knowledge-center/configure-cloudfront-to-forward-headers/

Could it be that you've configured apache to respond to requests for www.example.com and not ec2-xxxxx.amazonaws.com?

Answer

Hello,

Not Found error usually occurs when the Requested Object/File is not present in the Server or the Requested location, so can you please check the Server or the requested location if the particular requested file is present
