问题 AWS console(EC2 dashboard) shows public DNS name as ec2-99-xx-xx-xx.ca-central-1.compute.amazonaws.com for an EC2 instance. But the same AWS EC2 has a different DNS name (shown below): $ hostname -f ip-172-xx-xx-xx.ca-central-1.compute.internal compared to DNS name shown at AWS console. EC2 is created in default VPC.

问题 I'm trying to access https://flutter.dev, but I'm not able to. I'll get a spinner for 30 seconds, followed by this error: This site can’t be reached flutter.dev’s server IP address could not be found.

问题 I am trying to deploy multiple spring boot web applications with embedded tomcat in a single EC2 instance. With an embedded tomcat (I prefer to decouple my apps runtime), each one of these apps should be running on a different port (let's say 8081, 8082 and 8083). For each of these apps I would like to point a domain: app1.domaine.com should point to APP1 running on 8081 app2.domaine.com should point to APP2 running on 8082 app3.domaine.com should point to APP3 running on 8083 Do you think it
