hi 

I am getting below error when i am trying to run discovery for SUSE 15.1 devices.

error="Cannot connect, status is SSH_CONNECTION_FAILURE. Could not agree on client-to-server MAC algorithm&#10;Client: [hmac-sha2-256, hmac-sha1, hmac-sha2-512, hmac-sha1-96, hmac-md5-96, hmac-md5]&#10;Server: []" probe_time="564" result_code="1"><result error="Cannot connect, status is SSH_CONNECTION_FAILURE. Could not agree on client-to-server MAC algorithm&#10;Client: [hmac-sha2-256, hmac-sha1, hmac-sha2-512, hmac-sha1-96, hmac-md5-96, hmac-md5

As per my understanding, ServiceNow does not support ciphers to hmac-sha2-512-etm@openssh.com,hmac-sha2-256-etm@openssh.com. 

I looking for a way to get such devices discovered. Please share your suggestions
