Pretty sure this is a bug with tvOS, however open to suggestions.
Software = Infuse 7
Installed: Apple TV A1625 (tvOS 14.5), iPhone 12 Pro (iOs 14.5.1)
Network Drive = USB 3.0 Drive connected to an Asus AC86U router using Samba v1+v2
iPhone 12 = To put it simply, it works flawlessly with my iPhone 12. No issues whatsoever connecting to the network drive.
Apple TV (Issue):
Connection = WiFi
Description: Infuse has already “saved the share” due to the software being installed on my iPhone 12 Pro. Running a fresh install of the App and trying to connect, I get timeout errors and it refuses to connect to the network drive.
Infuse 4: For fun, I found an old version of Infuse 4 and installed that to my Apple TV. If I try to connect to the network share, it works as expected. No issues whatsoever.
I cannot help but think this has to be a bug that needs to be fixed. I’ve also opened a support request last Thursday for visibility.
