Please check your origin (ex. S3, HTTP backend) is active. If it is active, check the configurations like memory are sufficient.

Hi there
Please can you post more information about the setup you have? What is your origin server? How does CloudFront connect to your origin?
502 errors happen for a few reasons. When there is a host header mismatch or when CloudFront is unable to establish a DNS connection to your Origin server.
If you are using a custom Origin, make sure that you have the correct ports open, and that the Origin is internet accessible.
Make sure your certificate is valid and that it covers your Host name and any sub-domains you might be using.
