I'm not completely sure, but looks like the connection is getting closed by some part of the connection, like the server or the channel itself, but does not look like it's being intentionally closed by the app.

Does the SSH connection works well on another client, phone or pc?

[mtad2002]

yes it works on many other devices but on this specific device samsung galaxy s9 its not working properly
