Camunda 8 selfhosted fails in kubernetes

I have created a kubenetes cluster as a managed service on Scaleway, with camunda helm chart
The pods are mapped to 10.x.x.x addresses.
It seams that keycloak uses 100.x.x.x address instead of 10.x.x.x to get the readiness status, so the pods fail to start

I there a way to solve this issue ?
Thanks for your help
