I have been searching around for this problem, and have found other issues related but never a real solution... I have opened ports 8085 and 3724 within the firewall and restarted the firewall, yet when my app tries to connect it can't - I have tried it with the ports just being TCP, and TCP/UDP yet still nada - I know it is the ISPConfig firewall because as soon as I turn the firewall off, it connects fine, then I turn the firewall back on, and I can't connect anymore!! Why won't the firewall open those ports? Any help would be greatly appreciated!! Thanks!
