Roon remote cannot connect with roon core

Hello everyone,

My Roon remote cannot connect the core.

Recently, I have newly installed win10(64bit) and the newest roon since roon update didn’t work. Then my roon remote(iPad) cannot connect to the roon core.

It actually find the core but the connection didn’t happen. Always saying “connection failed”
Configuration roon OS also doesn’t find anything in the network.

Will you let me know how to solve the problem?

Thanks.
Lim.
