Hi Ricardo,
Was your HWC upgraded from a previous version (e.g. from 2.2 SP04?), or you are setting this with a brand new 2.3 SP04 iOS HWC installation?
I also just saw a similar problem reported and it turned out there was a compression module enabled on the Apache Relay Server that was causing issues. Disabling the Apache compression resolved the connectivity problem. Do you have something similar in your landscape?
Thanks,
Andrew.
