SSH Curl doesn't work when URL is accessible in browser

This post is linked with another post of mine (still unsolved):

Laravel - composer update: Connection refused

But I'm making another post about a more specific question.

On SSH, on prod server (shared hosting), I go to a specific folder (which contains my website):

$ cd /home/user/www/prod/

Then, if I try:

$ curl https://larapack.io/packages.json

I get: 

curl: (7) Failed to connect to larapack.io port 443: Connection refused

But if I do:

$ curl https://packagist.org/packages.json

It works.

Note that both files are accessible through my browser.

I've read several things on forums about IPv6 or firewalls, but:

EDIT: Trying other things...

It seems it's not a user agent/referer issue: (try with chrome 65 on windows 10)

$ curl -A "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3315.4Safari/537.36" https://larapack.io/packages.json

curl: (7) Failed to connect to larapack.io port 443: Connection refused

It seems it's not a IPV6 issue: (option -4 to force IPv4)

$ curl -4 https://larapack.io/packages.json

curl: (7) Failed to connect to larapack.io port 443: Connection refused

It seems it's not a ssl issue: (option -k to skip the ssl things)

$ curl -k https://larapack.io/packages.json

curl: (7) Failed to connect to larapack.io port 443: Connection refused

It seems it's not a firewall issue: I have a config file with valid directive firewall=none

It doesn't work with wget:

$ wget https://larapack.io/packages.json

pathconf: Value too large for defined data type

Resolving larapack.io (larapack.io)... 23.92.17.233
Connecting to larapack.io (larapack.io)|23.92.17.233|:443...

And neither with nc command (I don't have telnet command, but it works almost the same, as I could read)

$ nc larapack.io 443
larapack.io [23.92.17.233] 443 (https) : Connection refused

I tried to curl with php, and it works! So it seems it's only with SSH:

<?php

$url = "https://larapack.io/packages.json";

$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_URL => $url
));
$resp = curl_exec($curl);
curl_close($curl);

echo $resp;

Just one more thing to check in the case of working browsers but non-working curl is in-browser and system proxy settings (http_proxy, https_proxy environment variables for Linux).

For french developers using SSH with a shared hosting pro at OVH, the support says external calls like curl are disabled in ssh, but obviously I can do curl https://packagist.org/packages.json.

When they tried themselves, they got an error like action forbidden or something like that.

It doesn't make any sense.

I solved my prior issue doing composer install instead of composer update.

Here is the first discussion for reference: Laravel - composer update: Connection refused
