Installation without difficulty.
However, computers, smartphones and USB sticks (on the router) can only be seen sometimes. In most cases a new installation is necessary so that the folders can be read. Files can be opened. With "Upload File here" only the file name is uploaded, file size 0 bytes. Sometimes that doesn't work. Then the error "invalid port abcdef" is output. abcdf is the beginning of my password. (Very strange!)
What am I doing wrong?
"Invalid port abcdf" can be eliminated by restarting the smartphone. But why is only the file name uploaded?
