问题


Encountered redirect_uri error in keycloak. Found same issue logged at JIRA KEYCLOAK-7237, just want to check any work around? Anyone can help? Thank you in advance.

2018-06-30 11:34:13,996 WARN [org.keycloak.events] (default task-8) type=LOGIN_ERROR, realmId=Victz, clientId=portal, userId=null, ipAddress=, error=invalid_redirect_uri, redirect_uri=https://www.example.com:0/home

I am using apache http reverse proxy running on centos7, wildly 10, keycloak 3.4.3. has also tried in below environment but same error.

Tried in wildly 10, wildly 11, jboss 7.1, Keycloak 3.4.3 as well as keycloak 4.0

Also tried shutdown apache http and access directly to http://www.example.org:8080/home , but seems return_uri automatically been converted to https with port 0.

Please see below standalone.xml, tried removed below proxy-peer and request-dumper config but no luck.

I was having the same exact problem. My spring boot app sits behind nginx. I updated nginx to pass through the x-forwarded headers and updated the spring boot config with

spring boot yaml config:

server:
  use-forward-headers: true    

keycloak:
  realm: myrealm
  public-client: true
  resource: myclient
  auth-server-url: https://sso.example.com:443/auth
  ssl-required: external
  confidential-port: 443

nginx config:

upstream app {
   server 1.2.3.4:8042 max_fails=1 fail_timeout=60s;
   server 1.2.3.5:8042 max_fails=1 fail_timeout=60s;
}

server {
    listen 443;
    server_name www.example.com;

    ...

    location / {
        proxy_set_header        Host $host;
        proxy_set_header        X-Real-IP $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header        X-Forwarded-Proto $scheme;
        proxy_set_header        X-Forwarded-Host $host;
        proxy_set_header        X-Forwarded-Port   443;

        proxy_next_upstream     error timeout invalid_header http_500;
        proxy_connect_timeout   2;

        proxy_pass          http://app;
    }
}

The specific change that made it work for me was adding keycloak.confidential-port. Once I added that it was no longer adding port 0 in the redirect_uri.

Hope that helps.
