When I share my files to client FM Go 15 iPhone on my home wifi network, it works fine.  At work I'm allowed to access a limited "staff" authorized wifi, where the file share does not seem to work. Even when I repeat the process  (File/Sharing/Share with Filemaker clients) while on the work wifi, my FM Go does note recognize the host.  I do not have any access to the wifi here at work, beyond receiving the signal.  They use a third party admin and have no idea what could be done without engaging with and therefore paying for the troubleshoot call...  

Thanks for any help.  

Without insight to the network architecture there is no telling what to do.  Could be a routing/ firewall issue.  Basically the path on port 5003 needs to be open between the Go client and your host machine.

Are the FMP/FMS host and the iPad both on the 'staff authorised wifi'?
