Resolved FTP host name does not match certificate

[Phantasia]

Hello,
I secure my domains with Let's Encrypt wildcard certificates.
Every time I connect to one of my domains FileZilla shows the warning "Unknown certificate - host name does not match the certificate.

FileZilla Example:
General name: mymaindomain.com
Alternative names: *.mymaindomain.com, mymaindomain.com
Session details - server: myotherdomain.com:21 - host name does not match the certificate.

In this example myotherdomain.com is the domain I connect to via FTP and mymaindomain.com is the main domain of my root server.

This happens to all my domains - the certificate always shows the domain of the server but not the name of the domain I connect to.

OS: Ubuntu 14.04.5 LTS‬
Plesk Onyx Version 17.8.11 Update #21
Let's Encrypt: Version: 2.6.1-398

There is no possibility to install SSL certificate for a particular FTP domains.
