Hi,
I am getting connection reset by peer error while performing ssh to instance hosted in hong kong region. WHere as I am able to login on instance in other region and from there I am able to login on the instance on which I am unable to login using same key.

Error:
debug1: Connection established.
debug3: Not a RSA1 key file acs-hongk.pem.
debug2: key_type_from_name: unknown key type '-----BEGIN'
debug3: key_read: missing keytype

The key file that you are specifying is not a private key (Key Pair). Double check your command line syntax and the filename that you are using for the Key Pair.

Notice this line in your debug:

Not a RSA1 key file acs-hongk.pem

This means that they Key Pair is not an PKCS#1 private key, or is formatted in another format such as PKCS#8, etc. The RSA format needs to be PKCS#1 for the SSH program that you are using.

Open the acs-hongk.pem file. It should begin with this line. Anything else and it is a different format.

-----BEGIN RSA PRIVATE KEY-----

Thanks for your inputs @JohnHanley
Key file has -----BEGIN RSA PRIVATE KEY----- line
Just for your information,
Using same key file I am able to login from other instances to the instance on which I am unable to login from my network.

You can reset ssh password form the console.

Check first without ssh key in normal mode.
