Serv-U warning that no Server Identity (certificate) is configured

In Serv-U, a Server Identity is essentially the SSL/TLS certificate (and key) the server will use for secure services (FTPS/HTTPS, etc.). A dialog appears when you try an operation that requires SSL (for example enabling FTPS/HTTPS or completing some registrations) but no Server Identity is configured.

Cause

Tried to upgrade to 15.5 and got the error.

Resolution

To fix it, create or import a Server Identity, then retry the operation:

 

  1. Open Serv-U Management Console on the Serv-U server (run as administrator).
  2. Go to Global / Server Settings → Server Identity (exact menu name may vary slightly by version; look for Server Identity or Certificates).
  3. Choose one:
    • Create a new identity (wizard to create a self-signed certificate or CSR), or
    • Import an existing certificate (e.g., a .pfx/.p12 with private key).
  4. Complete the wizard and save the new identity.
  5. If applicable, go to the specific Domain → Listeners and make sure the new Server Identity is assigned to the FTPS/HTTPS listener you’re configuring.
  6. Repeat the action that previously triggered the popup; it should now proceed since a Server Identity exists.
