I´m having the error host not found in upstream “${BACKEND}” in /etc/nginx/conf.d/default.conf:2

share the docker-compose file used?

i think these variables may be missing or you may need to change it as per your container names.

try to format code/logs using three back quotes (`) for better readability.
