Cannot able to transfer file from bastion or jump server to EC2 instance.

While learning, I faced the issue of not being able to connect my bastion server or jump server to the EC2 instance for file transfer.
Here the solution:

1. Open your terminal.

2. Connect your bastion server with local system by ssh command.
   ssh -i /path/to/your-private-key.pem ec2-user@<Bastion-server-public-IP>

3. Open WSL(Windows Subsystem for Linux).

4. Run: chmod 400 /mnt/c/path/to/your-pem-key.pem

5. Run: ls -l /mnt/c/path/to/your-pem-key.pem

6. Run: scp -i ~/your-private-key.pem ~/your-pem-key.pem ubuntu@<Bastion-server-public-IP>.compute-1.amazonaws.com:/home/ubuntu/

   Thank you
