A company’s website is hosted on an Amazon EC2 instance. The website delivers dynamic content through Amazon CloudFront to users. After instance maintenance, users receive HTTP 502 (Bad Gateway) errors while attempting to access the website.
What is the MOST likely cause of this issue?
A. The security group configuration on the origin is blocking traffic from CloudFront.
B. The origin does not support the ciphers or protocols in the SSL/TLS exchange with CloudFront.
C. There are resource constraints, and CloudFront cannot route requests to an available edge location.
D. The origin does not have enough capacity to support the request rate.
