Server unexpectedly closed network connection

Greetings,

I am attempting to connect to an sFTP server using the .Net assembly. I have set the session options protocol to Sftp, our username, password, and hostname. I've obtained our host key fingerprint from the GUI, and even explicitly set the port number to 22.

When I attempt to open the session, I receive the exception 'Server unexpectedly closed network connection'.

Am I missing something?

Thank you!

UPDATE:

I've worked with the remote company, our IP was blacklisted. We have been removed from the blacklist.

Now I am receiving the error "Connection has been unexpectedly closed. Server sent command exit status 0." :?:

Thanks

That's still something THEY need to work out.

Prikryl,
Thanks so much! I worked with their EDI person to resolve the issue, our account was getting locked.

Also a word to the wise ... Notepad++ likes underlining hyperlinks, which makes a 'y' look like a 'v'. :oops:
