change web ui

Hi, I'm using this configuration so that it loads the modern web by default but sometimes it doesn't load the interface, and when I click on the back arrow in the browser, it returns me to the original interface of traccar, there is something that can be done.
here my configuration

 <entry key='web.path'>./web/modern</entry>

You have to recompile the modern app for the root path:

Thanks for the help
