If it is ip_tables, you can run these commands in order to fix the issue:

  1. sudo apt-get update
  2. sudo apt-get install ufw
  3. sudo ufw enable
  4. sudo ufw allow 443 (Where 443 is the port number to allow.)

There is documentation available for Ubuntu for this which is a similar process to the process for the Pi. This documentation is available at UFW - Uncomplicated Firewall.

EDIT: As this comment very rightly said, you must connect over HTTPS.
