Nextcloud login problem

[Hominem-Lot]

Hello everyone, I recently downloaded the Les Pas application. I tried the same operations both with the F-droid distribution and from the play store. After entering the address of my nextcloud and reaching the login page, when I enter the credentials (created specifically for the application) nothing happens. I press the "grant access" button and it doesn't work most of the time. Every now and then it goes back to the home screen and says "network error" both on WiFi and mobile networks. How could I solve it? The app is the latest published in F-droid on Google pixel 5
