On your website, I see that the container is loaded correctly, but all requests go directly to analytics.
Make sure that you have added your tagging server url https://ss.vanillebourbon.com to the server GTM container settings.
And please check in the web tags that the hits go to the server container and not to the analytics.

Thanks for the help, it’s all clear the header http was not correct so my server can’t receive anything
Another question, I have this on my dashboard:
“Warning
Preview header enabled. Don’t forget to disable it after debugging.”
I have to deactivate the HTTP Header Config power up ?
