putty error

plumberg

I have two laptops, connected on same Wireless network. One can connect to Kimsufi server via Putty, other cannot. I get "Server unexpectedly closed network connection".

Any quick way to troubleshoot and fix?

I tried ipconfig /flushdns, restarted the laptop.

You using IP or hostname?

Any 3rd party security/firewall running on the second laptop?

IP and hostname, both the same problem

This is my work laptop where it is a problem. Not sure if that will cause a problem as I was able to connect last week.

Update your putty client to the newest version.

Nope, newer security was put in place and older putty clients need to be updated to support it.
