I am using windows10 and I can connect to my server(Ubuntu 18.04) with PowerShell and Putty. but not with the other two ssh client I have (MobaXtrem,Bitvise). but when i turn on my VPN(SeedVpn) on client, I can connect with this two apps as well.
i wonder if this is a (Network,Firewall,Server) problem why Powershell and Putty working ? and if this is a problem with that two apps why with VPN i can connect? (also SFTP connection works on this two apps without VPN)
I did not set any rules on Server and I use Server IP as hostname not domain.
P.S. English is not my first language,sorry if there are grammatical mistakes.
