Default Timeout

The default timeout for Nginx is 60 seconds.

Settings

Update proxy timeout to 180 seconds:

http {
    proxy_connect_timeout 180s;
    proxy_send_timeout 180s;
    proxy_read_timeout 180s;
    ...
}

Java HTTP Client

Spring RestTemplate

Default Timeout

The default timeout is infinite.

By default RestTemplate uses SimpleClientHttpRequestFactory and that in turn uses HttpURLConnection.

By default the timeout for HttpURLConnection is 0 - ie infinite, unless it has been set by these properties :

-Dsun.net.client.defaultConnectTimeout=TimeoutInMiliSec 
-Dsun.net.client.defaultReadTimeout=TimeoutInMiliSec

Settings

@Bean
public RestTemplate restTemplate() {
    SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
    // Time to establish a connection to the server from the client-side. Set to 20s.
    factory.setConnectTimeout(20000);
    // Time to finish reading data from the socket. Set to 300s.
    factory.setReadTimeout(300000);
    return new RestTemplate(factory);
}

JavaScript HTTP Client

axios

Default Timeout

The default timeout is 0 (no timeout).

Settings

const instance = axios.create({
    baseURL: 'https://some-domain.com/api/',
    // `timeout` specifies the number of milliseconds before the request times out.
    // If the request takes longer than `timeout`, the request will be aborted.
    timeout: 60000,
    ...
});
