@Damian Emile From what I understand your Wowza and Wirecast configuration seems alright. The problem is occurring with your player. Can I know which player are you using? For example, is it PlayerJS, or JW Player, or Able Player, etc. Also, what is your website build on? For instance WordPress, or PHP, etc.
You can also try reading the article by Wowza on their players (you will need to browse around though): https://www.wowza.com/docs/media-players-and-devices
