hello folks

Exist problem about my account be free or our configuration can be with malfuntion. this happness only i try on “https://n8n.atitecnica.com.br/webhook/fb74d299-01da-4e92-bc1d-d5cca29f4db7/chat“ on selfhosted system on proxmox using lxc debian13. thank all

I believe the problem was solved by adding the “s”. In the compose.yml file, there was no “s” in http:\n8n.atitecnica.com.br in the current configuration. After including the “s”, everything worked.
