We have AWS ec2 with ubuntu Apache with ACM and AWS elastic load balancer, Sometimes it's returning "Error: Request timed out" ,sometimes works smoothly ,not able to identify real cause.
HTTP and HTTPS already allowed in security group , listener are added in load balancer for 80 and 443. also 80 request redirected to 443 port. CNAME added for ACM in route 53 health check is fine.
