Hi @zuber,

I assume that Jira is returning a detailed error message along with the 400 status code, so I suggest making sure that is printed first of all.

You can bump the log level of `RestTemplate` using `logging.level.org.springframework.web.client=DEBUG`, as described in [this StackOverflow post](https://stackoverflow.com/questions/7952154).

But I also recall coming across [SPR-9367](https://github.com/spring-projects/spring-framework/issues/14004), suggesting that the default `SimpleClientHttpRequestFactory` doesn’t support this, and that the best solution is switching the underlying HTTP client to Apache HttpComponents.

```auto
@Bean
public RestTemplateCustomizer httpComponentsRestTemplateRequestFactoryCustomizer() {
    return restTemplate -> restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());
}

```

Once you’ve done that, you can also bump `logging.level.org.apache.http=DEBUG`.
