Update your rclone to the latest version first - it is now v1.63.1

Is this sftp server working? Can you connect to it using e.g. FileZilla?

5

yes sftp connection works fine and I'm able to login to the server

6

I assume --sftp-user=<host_name> is just typo and you use user_name?

I am not sure how to go from here.

There is not much more debug we can get.

Connection fails - it would indicate something is wrong but no clue provided what it can be..

7

yes it was a typo. updated!

8

It would be worth taking a look at the server logs at this point if it is possible.

It might be something to do with that
