Solve the problem by Deploy Dash on apache server [solved!]
I just add these lines after app construction:
app = dash.Dash(
__name__,
server=server,
external_stylesheets=[dbc.themes.BOOTSTRAP],
# requests_pathname_prefix='/swatviewer/' # defining here will not work
)
app.config.update({'requests_pathname_prefix': '/<appname>/'})
