Prometheus connection with the backend

I have two services, one for my backend and another for Prometheus. How can I make Prometheus scrape my backend? I am using Nest.js for my backend. If you need additional information, I can share it.

Maybe it's because it's an HTTP connection and not an HTTPS connection?

it needs to be http, so you have that correct.

the pricate network is ipv6 only, so are you listening on ipv6?

this is my main.ts:

import { NestFactory } from '@nestjs/core'
import { AppModule } from './app.module'
import * as cookieParser from 'cookie-parser'
import * as dotenv from 'dotenv'
import { DocumentBuilder, SwaggerModule } from '@nestjs/swagger'
import { ValidationPipe } from '@nestjs/common'
import { AxiosInterceptor } from './axios.interceptor'
import { MetricsService } from './modules/metrics/metrics.service'
import { MetricsInterceptor } from './modules/metrics/metrics.interceptor'

dotenv.config()

async function bootstrap() {
const app = await NestFactory.create(AppModule)
const port = process.env.PORT || 3000
const isDevelopment = process.env.NODE_ENV !== 'PROD'

// Metrics setup
const metricsService = app.get(MetricsService)
app.useGlobalInterceptors(new MetricsInterceptor(metricsService))

app.useGlobalPipes(new ValidationPipe())
app.use(cookieParser())
app.useGlobalInterceptors(new AxiosInterceptor())

app.useGlobalPipes(new ValidationPipe())
app.use(cookieParser())

app.enableCors({
origin: [
links - i have the correct links here
],
credentials: true,
})

if (isDevelopment) {
const config = new DocumentBuilder()
.setTitle('VAULT | Wallet - SaaS API')
.setDescription('The documentation of all Wallet - SaaS API Project')
.setVersion('1.0')
.build()
const document = SwaggerModule.createDocument(app, config)
SwaggerModule.setup('api', app, document)
}

await app.listen(port, '::')
console.log(Server is listening on all interfaces (:::${port}))
}

bootstrap()

My question is: when I deploy, does the port my backend is listening on change every time?
