  I haven't seen that when I use SyncTerm, but I only use Telnet.  
    
  The error has to do with trying to set up the SSH connection.  
    
  "ECDH" is "Elliptic-curve Diffie-Hellman" and it's a method for 2 systems to  
  exchange a key without transmitting the key in the clear.  So that's why you  
  only see it with ssh.  Telnet isn't encrypted.  Ssh is.

  My guess is that SyncTerm is using an old library.  
    
  One thing that bit me with this at work had to do with TLS.  The older TLS  
  versions are being deprecated.  
    
  When the systems connect, they negotiate what version of TLS they will use.  
  Some systems don't negotiate correctly and try to use a deprecated version  
  of  
  TLS.  Policies on the computer may prevent that deprecated version of TLS  
  from  
  being used (either on the client or the host).
