Docker install error

[Benoît]

Hey,

After installing, when i go to adress, they ask Enter Encryption Password
But when i enter it, nothing, in the console i have this error

Uncaught TypeError: Cannot read property 'addEventListener' of null
    at Module.<anonymous> (bundle.js:1)
    at n (bundle.js:1)
    at bundle.js:1
    at bundle.js:1

I m using Nginx proxy manager

And i don't find the possibility to change the port for the creation on environnement variables, that is possible ?
