Spring Cloud Openfeign feign.RetryableException: Failed to connect to /127.0.0.1:80 executing POST http://127.0.0.1:8002/xxx

Describe the bug

<spring-boot.version>2.2.5.RELEASE</spring-boot.version>

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-openfeign-core</artifactId>
<version>2.2.9.RELEASE</version>
</dependency>

the main error trace, i think /127.0.0.1:8002 should be connected, not  /127.0.0.1:80

Sample If possible, please provide a test case or sample application that reproduces the problem. This makes it much easier for us to diagnose the problem and to verify that we have fixed it.

@FeignClient(name = "InfoApiClient", url = "",contextId = "InfoApiClient")
public interface ApiClient {

    @ResponseBody
    @RequestMapping(
            value = {"xxx},
            method = {RequestMethod.POST},
            produces = {"application/json"}
    )
    GetInfoResponse getInfoByIds(URI uri, @RequestBody GetInfoByIdsRequest request);

}

apiClient.getInfoByIds(new URI("http://127.0.0.1:8002"),request);

maybe this method need consider about the port? org.springframework.cloud.openfeign.loadbalancer.FeignBlockingLoadBalancerClient.execute String serviceId = originalUri.getHost();

Comment From: OlgaMaciaszek

Hi, @liuyinghus.t It does not seem like an SC OpenFeign issue. It seems that either there's nothing running at that host and port or it's not accepting connections. I can still take a look at this, but you would need to provide a minimal, complete, verifiable example that reproduces the issue (such as a link to a GH project with a small sample and instructions on how to reproduce the issue based on the code in the sample or tests that demonstrate it). Also, please learn how to properly format code and logs.
