Sorry, but this is a support forum for WinSCP SFTP client, not OpenSSH for Windows server.
I have installed OpenSSH 5_30_2016 64 Bit on a windows server 2012 R2 server (VM. I am having 2 problems with openSSH for windows.
(1) the sshd services keeps stopping randomly after I restart the services.
(2) After a time (24 hr) users can connect to the server it just errors out (yes the services are running), to get it to work I uninstall and reinstall the ssh services then it works.
I have formatted and reinstalled the server 2012 r2 and I am still having the problems.
