    Ask him to try a different FTP client in case he uses filezilla.

    he did, same problem.
    I watched him do that.

    no other clients reporting problems.
    So im confused what the problem can be

    To me it looks like there is an issue in establishing the SSL connection. Does the client maybe uses some kind of antivirus software or gateway which might put itself in between the FTP client and server? As a test, it might also be useful to see if FTP connection works without TLS (but change password right afterwards for security after doing an unencrypted login).

    yes without the TLS it is working. I have that now turned on
    ftp was turned off only ftps was supported by the server.

    i will report back to the client that he has to look in to his computers.
    there most be something on there that he has on both computers that blockes TLS.
