问题
I released my reactJs application. I have code information as below. But I get the error "11 # 11: host not found in upstream". where could i have made a mistake Could you help ?
I get an upStream error even though my docker, nginx, and docker-compose file is correct. I had run the same codes before but I could not find where I made changes.
default.conf
`
upstream frontend_server{
server web:3000;
}
server{
listen 80;
resolver 127.0.0.11;
location /.well-known/acme-challenge/ {
root /var/www/certbot;
}
location / {
return 301 https://$host$request_uri;
}
}
# SSL

listen 443 ssl;
resolver 127.0.0.11;
