Hi Khoi_Nguyen,

ssh_exchange_identification: read: Connection reset by peer

please update/upgrade your used SSH - Client, or use another one, because OpenSSH is removing support for "Diffie-Hellman group exchange" in old formats.

Please be reminded, that your issue does not depend to any Odin / Plesk - product, the issue is caused by your used SSH-client and the OpenSSH - version on your server and the depending SSL - libraries.
