502 Bad Gateway

>PROBLEM

Attempt to access the site returns:

502 Bad Gateway

>SOLUTION

Scenario: there is a server interfacing with external requests like Nginx or Apache.

In such cases, the application behind the Nginx, Apache, etc. may have stopped working, returning no answer.

Go to the application's log and check its state.

Make sure that it is responsive.

spring: spring boot: ERR_TOO_MANY_REDIRECTS

>PROBLEM

You try to access the site redirects to the default URL and the browser returns:

ERR_TOO_MANY_REDIRECTS

>SOLUTION

Edit your security class configuration that usually extends extends WebSecurityConfigurerAdapter.

Add the URL that fails.

@Configuration

@EnableWebSecurity

public class SpringSecConfig extends WebSecurityConfigurerAdapter {

@Override

protected void configure(HttpSecurity httpSecurity) throws Exception {

httpSecurity.cors().disable();

httpSecurity.headers().frameOptions().disable();

httpSecurity.csrf().disable()

.authorizeRequests()

.antMatchers("/", "THE MISSING URL HERE").permitAll()

//...

java: spring boot: How to search project issues in the stack trace

 

>PROBLEM

The application throws a lot of exceptions and you get confused to understand the cause because there are so many compiler complaints.

>SOLUTION

Follow by the example below.
If you go to the first compiler's complaint, you'll be mislead.

To find the real cause, the one that triggered the others, begin from the bottom to the top of the stack trace (the yellow in the example). 

The issue was caused for a field notation error. On the database the field is denoted by "pass" and not "password". Check the images at the bottom.
