Image not loading, Failed to open stream: HTTP request failed - php

I have the following problem on a Magento2 Fresh installation with dummy data, using the theme [Revo]: https://themeforest.net/item/revo-responsive-magento-2-shopping-theme/18339484
Error filtering template: Warning:
getimagesize(https://website.com/media/wysiwyg/imageslider/slider-1.jpg):
failed to open stream: HTTP request failed! HTTP/1.1 401 Unauthorized
in
/var/www/html/nobacco/vendor/magento/framework/Image/Adapter/AbstractAdapter.php
on line 304
Permissions are correct, nginx settings seem good the image exists on the server and is accessible through the same url and the user rights seems alright too.. Any ideas?
Before this error I was getting an error on vendor/(cant remember the full path)/Image.php

Reading empty AWS instance user data in Php causes Nginx error

I'm constantly getting this error in the Nginx logs:
FastCGI sent in stderr: "PHP message: PHP Warning: file_get_contents(http://instance-data/latest/user-data): failed to open stream: HTTP request failed! HTTP/1.0 404 Not Found
The reason is that http://instance-data/latest/user-data is the AWS instance user data which is empty for this server.
How can I still read user-data in PHP, even if it is empty, without getting the error?

A short commit:
#file_get_contents("http://instance-data/latest/user-data");

PHP file_get_contents sometimes failed to open stream Http request failed

I have an ajax call that gets many, many pages of contents from a website, but it fails to open steams sometimes even though the same exact links that failed to open streams works just fine, when I ran them again. The problem is, then other links would failed to open stream. Anyone know why this is happening?

need explanation for wordpress plugin error message

I'm trying to make a plugin work on my site. can someone explain clearly what this error message means?:
Warning: fopen(http://example.com/wp-content/plugins/zoomsearch/zoomsearch.css): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found in /home/me/example.com/wp-content/plugins/zoomsearch_wpplugin/zoomsearch.php on line 197

imagecreatefrompng() says that the URL returned a 404 error

i am trying to create a PNG resource from an image on a remote server, for that i use
$im = imageCreateFromPng('http://textures.minecraft.net/texture/7235ea086a4604e15e513c4add3935d64f23c535f9f62917c6d4886705ac8cf');
but when i execute the script it gives me this error:
Warning: imagecreatefrompng(*url*): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found
I tried to access the url above with my browser and the image loaded just fine, then i made a head request to that URL to see if the server sends a 404 header but i found out that it does not. so i have no idea how to solve this issue, thank you for reading.
EDIT
everything works just fine on another server i own, just not this one.
