title: Set ECDSA on Apache and get SSL_ERROR_NO_CYPHER_OVERLAP
body: <p>thats my first post. </p>
  
  <p>I will set up an Apache with ECDSA.
  I generates this keys
  secp256k1 : SECG curve over a 256 bit prime field
  secp384r1 : NIST/SECG curve over a 384 bit prime field
  and generate a self-signed certificate.</p>
  
  <pre><code>openssl ecparam -name secp256k1 -genkey -param_enc explicit -out rootCA.key
  openssl req -x509 -new -nodes -key server.key -sha256 -days 1024 -out rootCA.pem
  </code></pre>
  
  <p>At the ssl.conf I set</p>
  
  <pre><code>SSLCipherSuite ECDHE-ECDSA-AES128-SHA256:ECDHE-ECDSA-AES256-SHA384
  </code></pre>
  
  <p>Wireshark shows me that the client supports the cipher and i looked at firefox config</p>
  
  <p>The same cipher but with RSA cert works without problems. 
  I showed enough Tutorials but i cant find the problem.
  www.ssllabs.com/ssltest/ this test fails also with "Assessment failed: Failed to communicate with the secure server" </p>
  
  <p>Have someone ideas what I can do? </p>
