Can you run 

1. cfs la /coda   # show the access control list of /coda
2. ctokens        # show the coda token you currently have
3. cfs whereis /coda     # is the coda root volume hosted by your server ?
                         # or sometimes people accidentally point to 
                         # testserver.coda.cs.cmu.edu

and tell us the result ?

Also, you may want to read section 3 of the Coda Howto
  coda.cs.cmu.edu/doc/html/coda-howto.html
(just in case you missed it.)
