Unable to connect remotely with Redis based Nestjs microservice

Question

I have a Redis based dockerized microservice that I have deployed on a vps. In main.ts, this is how the service is exposed:

const app = await NestFactory.createMicroservice(AppModule, {
    transport: Transport.REDIS,
    options: {
        url: "redis://redis:6379"
    }
});
await app.listen();

The redis is the service name within the docker-compose.yml

I have it deployed on vps and it runs fine and I can ping/telnet to the server

The client app is a regular dockerized NestJS app that tries to connect to the microservice in the following way:

 ClientsModule.registerAsync([{
    name: "PAIGHAM_SERVICE",
    imports: [ConfigModule],
    useFactory: (configService: ConfigService) => ({
        transport: Transport.REDIS,
        options: {
            url: "redis://[IP-ADDRESS]:6379"
        }
    }),
    inject: [ConfigService]
}])

The IP_ADDRESS is the external IP assigned to the VPS hosting the microservice

But the client is unable to connect to the service. I also health-checked but it times out:

return this.health.check([
    () => this.microservice.pingCheck<RedisOptions>("service", {
        transport: Transport.REDIS,
        options: {
            url: "redis://207.180.210.3:6379"
        }
    })
])

I have no clue what wrong I am doing. Any immediate help would be highly appreciated.

UPDATE: This is doker-compose.yml for the microservice:
