Error listing a directory when using FTPES

[tomtom]

When connecting to host-europe over ftp + explicit ssl, filezilla cannot list directories after version 3.1.4 or so. IIRC there once was a discussion about a similar problem somewhere but ... Anyway, here is the transcript (in German sorry):

Broken server. Your host has to upgrade to a server that complies to the TLS specifications.
