Hello, we've decided to move our hosted apps that were on a Windows machine using NGINX server to a Ubuntu machine.
So we followed the same steps as we did on Windows; installed NGINX, moved the app files to the www folder and that's it.
But upon accessing the app through a browser many things aren't loaded like icons and such, and on the console I get the error "498" on some request to esri's server. According to google 498 means invalid token but I can't think why the generated token would be invalid in a Linux.
The problem is that we don't have any infrastructure specialist, we always relied on simplicity of Windows and now we are stuck in this problem.
