Hi @Anonymous
Try the following steps:
1) Go on to your Windows 10 computer and get the IP address by opening up Command Prompt and typing ipconfig and press enter.
2) Open up Microsoft Remote Desktop (while on the same network as your Windows 10 computer), clear the PC Name and type in the IP Address found above (IPv4) for the PC Name. In my example it would be 172.20.10.4
Try to connect to your host.
Note: If you are using a VPN so you can remotely connect to your host, then make sure that your VPN IP address on your iPad starts with the same digits as the IPv4 address (in my example it would be 172.20.10.x).
If this is helpful please accept answer.
