- Used Zammad version: 3.4.0-4
- Used Zammad installation source: docker-compose
- Operating system: Centos 7
- Browser + version: Chrome 84
Expected behavior:
Zammad can be accessed behind reverse proxy
Actual behavior:
Unable to access Zammad.
Steps to reproduce the behavior:
- Install zammad in docker compose behind Traefik
I’m unable to reach zammad installed via docker compose behind traefik. Error from nginx container is
