Yesterday I have created instance in aws server, which was working yestrday, but when I today start to connect with SFTP, I am getting error Network error : Software caused connection abort, also same error getting in putty, I am new in aws, so I don't have much knowledge of it, I read some doc of aws but it didn't help me, can anyone please help why this error getting ? As per my think, it because of ip address change of my internet, may be this can be the issue, but I don't know how to resolve this issue, can anyone please help me?

  • Can you telnet to your host's IP address on port 22 (assuming you are using default port)? The command to issue will be something like `telnet public-ip-address 22` (eg `telnet 123.123.123.123 22`). If you can, you know your network connection is OK. Also, please share details of the security group you have on your EC2 instance – Jorg Roper Jul 25 '18 at 06:11
