Cant login into to R11.1 sever edition with WinScp

[phoneTTech]

I am trying to login to a new R11.1.2.4 server edition with WinSCP. I read another string that I have to change PermitRootLogin to yes. That is done. I get the following error when I try.

Couldn't agree a key exchange algorithm. Please let me know if anyone has seen this. Thanks in advance!

Make sure you are on the very latest version of WinSCP.

“Some humans would do anything to see if it was possible to do it.
If you put a large switch in some cave somewhere, with a sign on it saying 'End-of-the-World Switch. PLEASE DO NOT TOUCH'.
The paint wouldn't even have time to dry.”
