Composer update not working since installing SSL certificate

问题

I installed an SSL certificate on my Ubuntu 16.04 server and since then composer has stopped working correctly.

The certificate works correctly when accessing the website through a browser. However, when running sudo composer update, I get the following warning:

The "https://packagist.org/packages.json" file could not be downloaded: php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution failed to open stream: php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution https://packagist.org could not be fully loaded, package information was loaded from the local cache and may be out of date

And then the following error:

 Updating dependencies (including `require-dev`)
  - Updating soundasleep/html2text (0.2.2 => 0.3.4)
    Checking out a1f77b8f340c8425b746bef1d1040189e89be334

    `Would you like to try reinstalling the package instead [yes]?`

If I try to reinstall it, it returns the following:

I already tried export http_proxy=myexternalip:80 and export https_proxy=myexternalip:443 (as well as HTTP_PROXY and HTTPS_PROXY but with no luck.
