FTP uploads to ftp.sophos.com not longer working due to TLS1.0 Handshake failure

Since this week me and my colleagues cannot upload files to ftp.sophos.com:990 over explicit TLS

happens to 195.171.192.29 and 195.171.192.30

Probably caused by Sophos Servers only offering TLS 1.0

Using filezilla latest version 3.56.0 with GNUTLS 3.7.2

Error:

Fehler:	Verbindungsversuch durch Benutzer unterbrochen
Status:	Warnung: Der gewählte Port wird üblicherweise von einem anderen Protokoll verwendet.
Status:	Auflösen der IP-Adresse für ftp.sophos.com
Status:	Verbinde mit 195.171.192.29:990...

Fehler:	GnuTLS-Fehler -8: A packet with illegal or unsupported version was received.
Status:	Verbindungsversuch fehlgeschlagen mit "ECONNABORTED - Verbindung abgebrochen".

Client Hello is TLS 1.2

Server Hello is only offering TLS 1.0

Can you please put this security level up again?
