Facebook Pixel via Matomo Tag Manger - Working in Preview but not working in Live Mode

Hello together,

I am currently trying to implement the facebook pixel on my companies website using the matomo tag manager.

In preview mode everything is working fine and the matomo tag manager is fireing. However, as soon as I publish the tag manger is not working anymore.

I was wondering if you could provide any tips how to debug this situation. I implemented the same setup in a different website were everything is working fine. There is no real difference in implementation, thats why I am so confused.

Following setup:

  • Matomo Version: Cloud hosted matomo
  • Integration of Matomo via: Vue.js and Nuxt SDK
  • Tag Manager: Using the dev environment
  • Publishing: on the dev environment

Thank you very much for your help.

Best regards,
