I read the guides and tried kind of "everything", but didn't succeed.....
I can connect to my QNAP NAS for example with:
NAME: KOPI-NAS (SMB)
at home, in the same network.
if I try to connect from "outside", I cannot connect
tried both ways to connect - like I connect to my NAS with the QFILE-App: (on my IOS iPad Pro)
Address: External IP (with or without Port), for example: 220.127.116.11:443
Always ends with "Sorry, error occurred during connection)
Help very much appreciated....
