    I bought a cheap certificate.
    When I send the CSR to the site issuing the certificate it says:
    "Challenge password in your CSR contains unsupported characters. Regenerate CSR using letters and digits only."
    I copied the CSR from "SSL Request" field (ISPConfig3).
    How can I solve it?

    I tried creating a new free SSL certificate using the same CSR without any problem so asked for support to certificate seller who says that the CSR was created with a challenge pass-phrase and suggest to avoid that.
    In "Web Domain > SSL" tab there is no such field.
    Is there a way to tell ISPConfig3 not to use a challenge pass-phrase?
    If not, can I create the CSR from scratch via ssh then manage it via ISPConfig3 interface?

    Not in the current version, the challenge password has been removed in 3.1.
