Consider the following scenario:
Note In this error message, the word "occured" is a misspelling of the word "occurred," and the word "implict" is a misspelling of the word "implicit."
Error details: Unable to connect to FTP server "<FTP Server name>" as user "<user name>". Inner Exception details: "An error occured while reading a response from the server. This could be due to the timeout settings. Also check whether the FTP server has SSL enabled and uses implict SSL as the FTPS connection mode. "
This issue occurs because of an error in the Xceedftpbiztalk.dll module.
When the FTP adapter uses the Xceedftpbiztalk.dll module, some SSL and TLS libraries send an empty (0-byte) data buffer as its first encrypted data buffer. However, the FTP adapter cannot decrypt an empty (0-byte) data buffer.
