[Kelunik\Acme\AcmeException]                                                                      
  Invalid response: JWS has invalid anti-replay nonce oJ29ZCkwqoQ4yg6NOHQHRbbQn5UpC77hTql5AGy87FM.  
  Request URI: https://acme-staging.api.letsencrypt.org/acme/new-cert.

This exception happens when I use the same AcmeClient and AcmeService instantiation to complete a challenge and then request certificate in one script. When I just do one of them, there is no such problem. I'm not sure what's the real issue (it may be my mistake), so I'd appreciate any troubleshooting help.

letsencrypt/boulder#1217 should actually be resolved. Nevertheless I added a retry mechanism in current master. See edb9404.
