Problem deploying my page in production

#angular #nginx #npm

I have 2 pages, each on a different server, but one of them does not work.
I started by using the production command ng build --prod --aot=true. After this I ran nginx.exe. With this in theory the frontend should be working.
When entering IP 127.0.0.1 on the server, the page appears but without the backend since the backend points to ljeans.mx.
For the backend I run pm2 start index.js -i 4. Once the command has been executed, if I go to https://www.ljeans.mx:3300/api/productos it works and gives me the result. So my problem is on the front but I can't find the problem. The issue here is that when I got to this job I realized that the domain is in IONOS and it points to the hostgator servers and in hostgator I have the redirection to my server.
this is my nginx.cong
