title: 404 error in spring cloud gateway for every alternate request
body: <p>I am encountering a very peculiar problem in spring cloud gateway. Every alternate request returns a 404. This happens across all services I've configured in the api-gateway without exception. I don't even know where to start to debug this problem. </p>
  
  <p>Here's my application.yml file for common config. </p>
  
  <pre><code>server:
    port: 8080
    ssl:
      enabled: true
      key-store: classpath:keystore.p12
      key-store-password: password
      key-store-type: pkcs12
      key-alias: tomcat

  <p>Here's my java config file</p>
  
  <pre><code>

          // Authenticate through configured OpenID Provider
          http.oauth2Login();
          // Also logout at the OpenID Connect provider
          http.logout(logout -&gt; logout.logoutSuccessHandler(new OidcClientInitiatedServerLogoutSuccessHandler(
                  clientRegistrationRepository)));

          http.headers().frameOptions().mode(Mode.SAMEORIGIN);
