Hi All,

I have architecture as below:

GCP Load Balancer (https://ssolb.xxx.com)
Keycloak Quarkus 17.0 installed in VM without Docker (https://sso1.xxx.com & https://sso2.xxx.com)
Frontend Apps (Next.Js)

Keycloak Conf:

db=postgres
db-username=keycloak
db-password=random
db-url=jdbc:postgresql://10.xxx.x.x/keycloak
https-certificate-file=${kc.home.dir}conf/chain.pem
https-certificate-key-file=${kc.home.dir}conf/key.key
proxy=reencrypt
hostname=sso1.xxx.com
https-protocols=TLSv1.3,TLSv1.2
https-port=443
metrics-enabled=true
cache-config-file=cache-ispn.xml
cache=ispn
log-level=INFO

When I use login with Keycloak, it will redirect to https://ssolb-xxx.com/realms/xxxrealms/protocol/openid-connect/auth

And then when I input credentials or using gmail, it will redirect to https://sso1.xxx.com/realms/xxxrealms/login-actions/authenticate and give me Cookies not found error

If check in browser console, it only give me 400 error when I login
POST https://sso1.xxx.com/realms/xxxrealms/login-actions/authenticate?session_code=oux54hhs3kWECp4iUN1QREliN6ZLjdJ6Nhb-HwQfIlM&execution=ff6d886b-23b2-44f4-b06b-366e63754be9&client_id=xxxxx&tab_id=w8Tf9OqxhAs 400

Anyone can give some hint related this? thanks

Hi,

I try to debug the http header and so far here are my found:

Via: 1.1 google
X-Forwarded-For: 180.243.11.xxx, 35.219.xxx.xx
X-Forwarded-Proto: https
Connection: Keep-Alive
host: ssolb.xxx.com

180.xx -> my notebook IP
35.xx -> LB IP

So basically GCP Loadbalancer Add LB IP in X-Forwarded-For after Client-IP.
And I also found the header host is lowercase
Does Keycloak OK with this?

I also found my endpoint is mixed between https://sso-lb.xxx.com and https://sso1.xxx.com.
