I had the same problem and I solved it setting up logs for DotNetOpenAuth (http://www.dotnetopenauth.net/developers/help/loggingdebugging-dotnetopenauth-with-log4net/). If you are using Log4Net you can try this:

<appender name="FileApp_DotNetOpenAuth" type="log4net.Appender.RollingFileAppender">
    <file value="Logs/DotNetOpenAuth.log" />
    <appendToFile value="true" />
    <rollingStyle value="Size" />
    <maxSizeRollBackups value="10" />
    <maximumFileSize value="5MB" />
    <staticLogFileName value="true" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
    </layout>
  </appender>

<logger name="DotNetOpenAuth">
    <level value="ALL" />         
    <appender-ref ref="FileApp_DotNetOpenAuth"/>
  </logger>

Then check the log file DotNetOpenAuth.log for your current error. It would help you troubleshoot the problem.
