502 Bad Gateway: when I try to download an excel file !

Hello,

I'm using Maatwebsite/excel but when I try to download an Excel file it returns me :

502 Bad Gateway
nginx/1.18.0 (Ubuntu)

This problem happens in all envs also in my local env (vagrant).

Any Idea ?

Also how to get the nginx logs ?
