SSH Host Key fingerprint does not patch pattern - c#

I have located the problem. It was to do with the length of the Host Key, which I compared with another site that is working. I shortened the key and after a few more tests (I had a Peer certificate rejected), I got it to work.

Here is the amended section: 
SessionOptions sessionOptions = new SessionOptions
{
    Protocol = Protocol.Ftp,
    FtpSecure = FtpSecure.ExplicitSsl,
    HostName = "xxxxxxxxxxxxxxxxxxx",
    UserName = "xxxxxxxx",
    Password = "xxxxxxxx",
    GiveUpSecurityAndAcceptAnyTlsHostCertificate = true
};

SSH Host Key fingerprint does not match pattern – C#

Hi,

I am trying to connect to an FTP site running explicit FTP over TLS, but the script trips over the Host Key fingerprint: 
SessionOptions sessionOptions = new SessionOptions
{
    Protocol = WinSCP.Protocol.Ftp,
    FtpSecure = FtpSecure.ExplicitTls,
    HostName = "xxxxxxxxxxxxxxxxx",
    UserName = "xxxxxxxx",
    Password = "xxxxxxxx",
    SshHostKeyFingerprint = "ssh-rsa 2048 bb:9c:4c:05:f8:25:2b:8f:80:a3:75:b7:94:5c:ea:9f:fc:b2:12:18"
};

This is the information from the FTP site: 
Remote system = UNIX Type: L8

File transfer protocol = FTP

Cryptographic protocol = TLS Explicit encryption, TLSv1

Encryption algorithm = TLSv1/SSLv3: IDEA-CBC-SHA, 2048 bit RSA

Compression = No

------------------------------------------------------------

Certificate fingerprint

bb:9c:4c:05:f8:25:2b:8f:80:a3:75:b7:94:5c:ea:9f:fc:b2:12:18

------------------------------------------------------------

Can change permissions = Yes

Can change owner/group = No

Can execute arbitrary command = Protocol commands only

Can create symlink/hardlink = No/No

Can lookup user groups = No

Can duplicate remote files = No

Can check available space = No

Can calculate file checksum = No

Native text (ASCII) mode transfers = No

------------------------------------------------------------

The additional information shows Fingerprint (SHA1): 
bb:9c:4c:05:f8:25:2b:8f:80:a3:75:b7:94:5c:ea:9f:fc:b2:12:18

On attempting to connect I get the following error:
SSH host key fingerprint \"ssh-rsa 2048 bb:9c:4c:05:f8:25:2b:8f:80:a3:75:b7:94:5c:ea:9f:fc:b2:12:18\" does not match pattern /(ssh-rsa |ssh-dss )?\\d+ ([0-9a-f]{2}:){15}[0-9a-f]{2}(;(ssh-rsa |ssh-dss )?\\d+ ([0-9a-f]{2}:){15}[0-9a-f]{2})*/

Can anyone point me in the right direction?
