Hi Buser,Thank you for using the Xerox forum.The 6204 is most often dependant on the Accxes server; Those installation instructions can be found in the Documentation section of the 6204 Support site
There is also a solution related to installing 6204 in the support section of that same site and I would suggest that you review that following solution. 6204 without Freeflow Accxes?
If these do not resolve your issue you may consider contacting our specific product support experts at the following link:Fast Track to the Expert
