Inhouse built Spring Boot Rest API consumes a 3rd Party REST API

Question

Any suggestion here is highly appreciated.

I am building a Rest API (/inhouse) using Spring boot, which should call a third party API (/team).

End Goal:

/inhouse API {
   Sets Header and does a Get call on /team (3rd party API)
   Parse the response and apply some business logic
   Return the final data in JSON format
}

Front end Angular will utilize the final data

@GetMapping("/inhouse")
    public String getInhouse() {        
        RestTemplate restTemplate = new RestTemplate();
        HttpHeaders headers = new HttpHeaders();
            headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
             headers.add("Authorization", "Basic " + aut);
                HttpEntity <String> entity = new HttpEntity<String>(headers);

          return restTemplate.exchange(apiUrl, HttpMethod.GET, entity, String.class).getBody();

    }

I'm currently getting an error:

java.net.ConnectException: Connection timed out: connect] with root cause

I'm not sure if it will solve your problem, but it would worth a try:

@Bean
public RestTemplate restTemplate() {
  return new RestTemplate(new HttpComponentsClientHttpRequestFactory());
}

(I assume you had already tried accessing that endpoint manually from browser and it worked.)

Unfortunately the issue was missing Proxies. The error message "Time Out" was really misleading. Once I added missing proxies, it worked.

Thanks for the help.
