            @PathVariable String from, @PathVariable String to, @PathVariable BigDecimal quantity)
    {
        
        CurrencyConversionBean response = proxy.retrieveExchangeValue(from, to);
        return new CurrencyConversionBean(response.getId(),from,to,response.getConversionMultiple(),
                quantity,quantity.multiply(response.getConversionMultiple()),response.getPort());

I found the solution for above issue, Spring boot version 2.7.9 wont support Ribbon Loadbalancer, so i downgraded my spring boot version from 2.7.9 to 2.3.1.RELEASE.

Before pom.xml

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.7.9</version>
        <relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
        <java.version>1.8</java.version>
        <spring-cloud.version>2021.0.6</spring-cloud.version>
    </properties>

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
            <version>2.1.2.RELEASE</version>
</dependency>

After Changed my spring boot Version

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.1.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
        <java.version>1.8</java.version>
        <spring-cloud.version>Hoxton.SR5</spring-cloud.version>
    </properties>

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
            <version>2.1.2.RELEASE</version>
        </dependency>
