Hello Pradeep,

Did you get a chance to see the above pom.xml file? please help if you can find something in the pom.xml.

Hi @ammar,

Yes. I took your pom.xml, did setup able to open camunda page.

Thing is that you are using spring security that is blocking all your request.

I created the below pseudo java code to test.
Please read about Camunda with spring security that may help you to setup in your end.


@EnableWebSecurity
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {

	@Override
	protected void configure(HttpSecurity httpSecurity) throws Exception {
		httpSecurity.csrf().ignoringAntMatchers("/rest/**")
		.csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
		httpSecurity.logout().disable().formLogin().disable().authorizeRequests().antMatchers("/**").permitAll();
	}

}

HI @pradeep,

I have tried the above code snippet with my application, but still same error. I am using the below securityConfig:

@Override
protected void configure(HttpSecurity http) throws Exception {
	http.cors().and().csrf().disable().exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
			.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and().authorizeRequests()
			.antMatchers("/", "/favicon.ico", "/**/*.png", "/**/*.gif", "/**/*.svg", "/**/*.jpg", "/**/*.html",
					"/v2/api-docs", "/configuration/ui", "/common/**", "/v2/api-docs", "/configuration/ui",
					"/static/downloadFile/**", "/resources/**", "/swagger-resources", "/configuration/security",
					"/swagger-ui.html", "https://aqueous-cliffs-46108.herokuapp.com/api/customer/get/customer/api",
					"/webjars/**", "/**/*.css", "/**", "/**/*.js")
			.permitAll().antMatchers("/api/auth/**").permitAll().antMatchers("/api/geolocation/**").permitAll()
			.antMatchers("/api/ticketTemplate/**").permitAll().antMatchers("/api/admin/**").permitAll()
			.antMatchers("/api/ticket/**").permitAll().antMatchers("/api/image/**").permitAll()
			.antMatchers("/api/customer/**").permitAll().antMatchers("/api/application/setting/**").permitAll().antMatchers("/api/otp/**").permitAll().anyRequest().authenticated();

	// Add our custom JWT security filter
	http.addFilterBefore(jwtAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class);

}

I have removed all security Coinfig and run the application. Then the login screen of camunda comes but without styling and when I entered the credentials it says wrong user credential error message.
