AWS EC2-连接超时-SSH

Question

I am new to AWS. Luanched an EC2 instance and set it up to server a Laravel application. Out of nowhere I am not able to SSH into the instance (which was working fine)

Network error: Connection timed out

The application is accessible through browser. But not able to SSH into the instance.

Answer 1

Since your application is accessible for browser, I hope you know how to configure the inbound connections. I believe your machines IP address has changed due to which you are not able to access. Your IP can change if you have reset/switch on/off the Internet or if you are connecting from a different Internet connection after the initial server configuration.

You need to follow these steps

Open the inbond connection for SSH
1. EC2 bashboard - > click the respective Security Group
2. Select the Public SG - > click inbond tab
3. Add an entry SSH | TCP | 22 | Select MyIP

Answer 3

Could it be that you are trying to SSH into the instance from a corporate network, or one that does not allow outbound connections on port 22 (ssh) ? See my answer here: https://stackoverflow.com/a/45634848/981913
