WindTerm can't connect via SSH, but MobaXterm can

The same server, both intranet and extranet should be accessible via SSH

WindTerm
intranet can not access a specific server, whether or not with a domain name, or IP address, prompting Timeout connecting to 192.168.80.253, when I connect again, he will appear white screen loss of response, for this problem I am verifying whether to open SFTP results are the same

The same moment
I use MobaXterm to connect to the same server, whether with IP address or domain name he can access very smoothly

I don't know what the problem is, I tried to delete the connection and re-establish it, but the problem is still the same

Start by reproducing the SSH connection failure to 192.168.80.253 using both its domain name and IP address, including the SFTP attempt. Compare the timeout and subsequent blank, unresponsive screen with a successful MobaXterm connection. Done means WindTerm can connect reliably to the same server over SSH and SFTP.
