title: traefik's tls: client didn't provide a certificate when accessing https endpoint
body: <p>Here's my configuration</p>
  
  <pre><code>[entryPoints]
    [entryPoints.http]
    address = ":801"
  
    [entryPoints.https]
    address = ":802"
    [entryPoints.https.tls]
      [entryPoints.https.tls.ClientCA]
        files = ["/etc/ssl/comodo/bundle.crt"]
  
        [[entryPoints.https.tls.certificates]]
          certFile = "/etc/ssl/comodo/www.crt"
          keyFile = "/etc/ssl/comodo/www.key"
  
  [frontends]
      [frontends.http] # default
        entryPoints = ["http", "https"]
        backend = "fallback"
        passHostHeader = true
  </code></pre>
  
  <p>Now I'm trying to access <a href="https://mydomain:802" rel="nofollow noreferrer">https://mydomain:802</a> and I get following error in traefik debug output
  <code>http: TLS handshake error from 111.111.111.111:64463: tls: client didn't provide a certificate</code></p>
  
  <p>curl error message
  <code>error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate</code></p>
  
  <p>I can't figure out what I'm doing wrong.</p>
