Hi,
since an external FTP Server with Cerberus FTP 8.0 has changed to FIPS, Core FTP Pro isn't able to connect anymore.
Connecting with FileZilla or Putty SFTP to this server works fine. I don't have further informations about what exactly has changed, but the servers description changed from SSH-2.0-CerberusFTPServer_8.0 to SSH-2.0-CerberusFTPServer_8.0 FIPS.
Output of connection attempt before change:
SSH-2.0-CerberusFTPServer_8.0
ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1
client cipher -> aes256-ctr
client->server mac : sha2-512
server cipher -> aes256-ctr
server->client mac : sha2-512
Output of connection attempt after change (replaced the real hostname with ftp.example.com):
SSH-2.0-CerberusFTPServer_8.0 FIPS

Already tried to change Advanced Settings -> SSH -> "Use Putty compatible SFTP" and "FIPS mode", but didn't help.
Using Core FTP Pro v 2.2 build 1922.
Any suggestions?
