I am in need of assistance with my Meta's Conversion API and Google Tag Manager setup. I have successfully set up a web and server container, with the server container being manually configured and running on AWS.
I am currently working on the "Publish resources" section, but am encountering an error that says "Publishing failed. We were unable to publish the resources to your Google Tag Manager account. Please try again." I would greatly appreciate it if someone could provide some guidance in resolving this issue.
For reference, my web container is running on web.example.com, the tagging server is running on tagging.example.com, and the preview server is running on debug.tagging.example.com. I have followed this guide to set up my server-side tag manager on AWS: deploy-server-side-google-tag-manager-aws/.
Here are some screenshots:
I google-searched for this error and all I can find is other people with the same error but no solution was provided. I have also emailed Google and Meta support but I haven't gotten a response yet.
