The apex code which I am writing is

        String locale = 'en';
        userGroup=System.Label.UserGroup;

        // System.debug('>> encryptedkey >> ' + encryptedKey);

From SOAP UI WHEN I AM PASSING THE TOKEN, Error which I am getting is

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <soap:Fault>
         <faultcode>soap:Server</faultcode>
         <faultstring>Fail creating session for token 'oEP0N1VHM4yLFOytdDwSSRpuXsW+s4LMnypVDYU8/X8q4vznJ0epj60Rhce8ksw/'.</faultstring>
