Can't connect to a remote Centos 7 server via SSH with anything, except Putty

Can’t connect to a remote Centos 7 server via SSH with anything, except Putty. Filezilla and WinSCP don’t work, connecting from Linux File manager also doesn’t work, but connecting from Putty and connecting from Linux terminal works just fine. P.S. I’m connecting as root.

WinSCP log says that the access has been granted, but connection just freezes after that.

WinSCP log (I’ve changed IP and domain name):
