Nginx is looking for a favicon.ico file at the root level.
Instead, for Laravel projects, it should look in the public folder.

Just add /public on the files paths inside your config file, and run valet restart:

location = /public/favicon.ico { access_log off; log_not_found off; }
location = /public/robots.txt  { access_log off; log_not_found off; }

If you have run valet secure, you'll find your app's config file here: ~/.config/valet/nginx/your_app.test

Otherwise, the default valet nginx config file is located here:
/usr/local/etc/nginx/valet/valet.conf

Perfect! This does the trick.

If you need to update all the projects, you can run this sed command.

Bash
sed -i 's|location = /favicon.ico|location = /public/favicon.ico|g; s|location = /robots.txt|location = /public/robots.txt|g' /etc/nginx/valet/valet.conf

or ZSH / Mac
sed -i '' 's|location = /favicon.ico|location = /public/favicon.ico|g; s|location = /robots.txt|location = /public/robots.txt|g' /etc/nginx/valet/valet.conf

And then:
valet restart

And problem solved!
