An error occurred during the configuration of the host information

During the IVS installation process, an error occurred during the configuration of the host information, and the message "Failed to connect to the SFTP server to obtain the file" is displayed.

In the configuration host information step of installing the eSpace IVS system, the detailed configuration information is as follows: 80 is the linux server, iDeploy is deployed on my local machine, this machine is the 2008 system, the ip is 101, and the prompt message when the configuration is completed is " Failed to connect to the SFTP server to obtain files", then check the iDeploy log and found the following error "ssh: connect to host port 1127: Connection refused", why is the port 1127, I use the Xftp tool to connect to the linux ftp connection, which is used here The port is 22, how do I deal with this kind of problem. Where is the configuration problem?

Thanks
