Nextcloud work in Android App, not in browser

Hi, I have a problem with my new installation of Nextcloud.
My server works when I use the android application but not with my internet browser.

I have this menu but I can not click on anything, however the storage that we see at the bottom left of the screen varies if I add files by the application.

Do you have an idea?

Thank you.

Just a hint which information a help request should usually include to be more successful:

  • Which Nextcloud version is being used in which environment.
  • Which web browser are you using.
  • What have you done to cross-check that it isn’t a general error, like using a different browser on a different device.
  • Are there any messages in the Nextcloud log at the time you try to access the server.
  • etc.
