Unsupported or unrecognized SSL message

The following error may appear when publishing to a web server via FTPS:

Could not connect to FTPS server (host:21) : Unsupported or unrecognized SSL message

This error occurs when the FTPS Transport is configured to connect to a target server using explicit FTPS over port 21. Cascade CMS currently supports implicit FTPS only, so the steps to correct this are as follows:

• Configure the target FTPS server to allow implicit connections (typically over port 990)
• Adjust the corresponding FTPS Transport in Cascade CMS to connect using port 990
