An implicit FTPS client can't connect to the FTPS server using TLS.
FTP client can't use implicit FTPS if Verified Accept is enabled.
-- FTP client uses implicit FTPS. -- The BIG-IP has an FTP Virtual Server with TCP verified accept option enabled.
1. Do not use implicit FTPS variation of FTP protocol. It is obsolete option. The regular FTPS is working well. 2. Remove Verified Accept (VA). the implicit FTP is working well without VA.
