No

Are you able to login with any other SSH client?

Hello. I cannot connect to remote server, it returns "Server unexpectedly closed network connection" error. I guess that it has something to do with our new network that we have installed few days ago and now I am connected through router.

Here is a log, if you need more information, just ask :). Thanks
