Identity white page issue

Hi Team ,Kindly help to resolve my issue …
In identity user credentials entry prompt page is opening through the browser but when entered the credentials it’s giving the white blank page not the expected one…


I was tried to run default setup with ingress enabled
My setup info :
Ingress enabled …
/etc/hosts content
192.168.xxx.xx camunda-platform zeebe.camunda-platform
Used nfs-storageclass …
Certficates → created using ca issuer in cert manager …

[root@linux default]# k get cert
NAME                READY   SECRET                    AGE
camunda-host-cert   True    camundahost-cert-secret   26h
zeebe-pod-cert      True    zeebe-cert-secret         26h

My modified entries in values.yaml file:

All the pods were running and i could able to connect through the browser using the urls(https) except identity …

Helm status info

Default user and password: "demo/demo"
## Combined Ingress
- Keycloak Authentication: https://camunda-platform/auth
- Web Applications:

  - Identity: https://camunda-platform/identity
  - Operate: https://camunda-platform/operate
  - Optimize: https://camunda-platform/optimize
  - Tasklist: https://camunda-platform/tasklist

In identity pod i got logs like below

camunda.identity.sdk.impl.rest.exception.RestException: request failed with status code '400' and body '{"error":"invalid_grant","error_description":"Invalid token issuer. Expected 'http://camunda-keycloak/auth/realms/camunda-platform'"}'

If i change publicIssuerUrl: “http://camunda-platform/auth/realms/camunda-platform” the invalid token error is not coming in identity pod …Still after given the identity credentials in the browser -->blank white page only appeared …
