Required ports for WhatsApp07 Jan 2019
Ran into a little fun time at work recently. A user was intermittenytly seeing WhatsApp fail to connect. Poked around for a bit and figured out that we didn’t have all the required ports open on our guest wifi network. I spent a while trying to track down a definitive list of ports that are necessary for WhatsApp. Found some dated and inaccurate references scattered around, but finally got a true list from their support team. Enjoy!
