Filezilla GnuTLS error -15: An unexpected TLS packet was received

Using a wildcard certificate to connect to a newly configured VSFTP server on CentOS on FTPes, I got the following error:

Status: Resolving address of www.ezref.info

Status: Connecting to 216.194.168.36:21...

Status: Connection established, waiting for welcome message...

Response: 220 (vsFTPd 2.2.2)

Error: GnuTLS error -15: An unexpected TLS packet was received.

Error: Could not connect to server

Since FTPes was not working, I decided to use plain FTP. That's when I realized my mistake.

I was using virtual users to connect and missed out on creating the folders on the server.

So I went ahead and created the required folders, changed the ownership and test again with plain FTP, it worked!

I switched back to FTPes and tested again and that worked too!

Bottom line: GnuTLS error may not necessarily be due to certificate errors.
