laravel passport is installed is it related to anything?

Its ca-certificates error on your server

This error is related to a missing package: ca-certificates. Install it.

In Ubuntu Linux (and similar distro):

# apt-get install ca-certificates
In CygWin via Apt-Cyg

# apt-cyg install ca-certificates
In Arch Linux (Raspberry Pi)

# pacman -S ca-certificates
