Missing SSL / broken links

[kostasx]

The following link on the website (https://pionerasdev.co/) is leading to a 404:

• Footer [Síguenos en] > GitHub > redirects to: https://github.com/pionerasdevelopers

Also, the site is lacking an TLS/SSL certificate which prevents certain browsers from displaying the website (the message "Your connection is not private" is being displayed). Same issue affects the https://workshop.pionerasdev.co/ and https://en.pionerasdev.co/ subdomains.

Keep up the great and inspiring work! 🚀
