EC2 Instance suddenly cannot connect to Internet

0

Need help on my Instance. My instance suddenly cannot connect to the internet, but can do ping to google. If you ask how about the VPC or Network configuration, the VPC itself used in different EC2 instance and the instance can connect to the Internet.

The pic below is screen shot for apt update apt update failed

Have you taken a look at this troubleshooting guide - https://aws.amazon.com/premiumsupport/knowledge-center/ec2-connect-internet-gateway/#:~:text=To%20troubleshoot%20why%20your%20Amazon,isn't%20blocking%20the%20access.

If it still does not work, you may have to enable VPC Flow logs in your VPC to determine the root cause - https://docs.aws.amazon.com/vpc/latest/userguide/flow-logs.html

    Hi, currently I have no issue with the VPC, SecurityGroup or Route, since the VPC is used in different EC2 instance and running without issue with the internet. And the firewall inside the server is currently disabled
