what this log mean ?

List to check:

  1. client server are in same version
  2. the password are same
  3. cipher and auth mode are same
  4. there are no transparent proxy between client and server

If they are all correct, then maybe your VPS or ISP doesn't allow raw socket's packet to passthrough correctly.
