Ipad app unable to see Minimserver

[mgohlke]

The Mind 280D app has stopped being able to see the Minimserver. I followed all the directions on the troubleshooting (Windows 10) page, including checking ip subnets, firewall settings, cycling power on the wifi router, PC which is running the minimserver, the Mind (a Moon audio DAC for music), and the control point (Ipad). I also checked to see that the Mind app and the Minimserver are up to date. Everything else associated with WiFi and various apps and devices works. Please advise what to do next
