if __name__ == '__main__':
    app.secret_key = 'super_secret_key'
    app.debug = True
    app.run(host='0.0.0.0', port=5000)

это код wsgi

import sys

logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,'/var/www/Catalog/')

from App import app as application
application.secret_key = 'super_secret_key'

это модификация кода конфигурациитолько мне нужно, чтобы он тоже работал на сервере, а не только на localhost

WSGIScriptAlias / /var/www/App.wsgi

, и ошибка не может открыть файл БД или не удается найти флягу. хотя он установлен и локально работает файл БД
