This is in a few places

Make sure the OCSP responder is running:
  cd <wolfssl-dir>
  openssl ocsp -port 22221 -ndays 365 \
      -index certs/ocsp/index-intermediate1-ca-issued-certs.txt \
      -rsigner certs/ocsp/ocsp-responder-cert.pem \
      -rkey certs/ocsp/ocsp-responder-key.pem \
      -CA certs/ocsp/intermediate1-ca-cert.pem
