Cookie Not Found - HA - GCP Load Balancer

Configuring the server
1

Hi All,

I have architecture as below:

  1. GCP Load Balancer (https://ssolb.xxx.com)
  2. Keycloak Quarkus 17.0 installed in VM without Docker (https://sso1.xxx.com & https://sso2.xxx.com)
  3. 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

image

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
image

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

I also tried 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

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

  1. Does Keycloak support host header in lower case?
  2. Does Keycloak OK with additional ip adresss (LB IP) in X-Forwarded-For? GCP seems have to append LB IP in X-Fowarded-For and I couldn’t delete it
  3. Any hint for this Cookies not found? Very appreciate, because it already takes a week troubleshooting :frowning:

Yes, it does

Yes, it does

  1. Any hint for this Cookies not found? Very appreciate, because it already takes a week troubleshooting :frowning:

The answer is hostname=sso1.xxx.com should be changed to hostname=ssolb.xxx.com for all machines, so all cookies and page redirection will be setup as ssolb.xxx.com

Where do you set those settings ? I have the same problem but I can’t find where they are set in my case, some are set to the front end ui endpoint.

Did you guys find any solution to this? I’am facing the same issue.
