Not able to connect ssh - for AWS server - (error). - keypair.perm permission deny OR keypair.pem does not exist?

 

Solution to below issue ( in Mac)

Could not find /Users/keypairs/key-pair.pem

Connecting to: server  at IP 90.xx.x.xxx with keypair key-pair

Warning: Identity file /Users/key-pair.pem not accessible: No such file or directory.

ec2-user@90.xx.x.xxx : Permission denied (publickey).

Try this :

1. In terminal - Go to the path where the "key-pair.pem" is sitting.

2. Check the permissions - just why typing the command - 

            c:/Users/keypairs>   ls -la

3. Run the command - 

          c:/Users/keypairs>   chmod 400

or       c:/Users/keypairs>  chmod 600

This should resolve the issue-- At least this worked for me!
