hello
I bought a new device (f2-425) and installed the hard drive, then detected it on the network. I set it up completely, created the names and spaces, and then tried to access it via the mobile app, but every time I get an error message (invalid username or password) . I looked for solutions, but they all failed, so I deleted everything and started over, but with no result—same error message every time. Are there any solutions?

This is an extremely rare situation with almost no precedents. What version of TOS are you using?
If you try creating and using another account with a simple username and password, are you able to log in successfully on the TNAS mobile app? If the password is too long, perhaps you could try copying it from your computer, sending it to your iPhone, and pasting it there? Also, please be sure to check the case sensitivity of your username.
