FTP Issues Only on Pie

[VWRacing07]

Hi,
I have an FTP server setup that I can access just fine from my PC and my tablet on Android 8.1, but on my phone, using the same app as my tablet, it shows my ftp drive as "empty". I have tried other apps and get similar results, but only on my phone on Android 9. (Moto Z3 Play)

I don't have any firewall apps or anything. Anybody have any ideas why this would happen only on my Pie device?

Update: No reason found, but the solution was doing a factory reset of my network settings.
