Wing FTP Software

i notice some issues when users login to web interface, if a user's public IP addresses keep changing, for example, when visiting through AWS, the user's connections got dropped (cannot login) or the user receive 'Session Expired' error in their browsers.
the server version is 6.0.7.
don't know if it's the same issue from sftp, very few users using sftp.
any idea? thank you

Yes, correct, the web session will expire if client IP changes, it is a security design.
