Awx web login failed

I have just deployed awx-operator v2.19.1 via helm chart GKE with external manged POSTGRES on GCP

But I cannot login to the web UI with the following error:

awx web login error POST https://my.custom.domain/api/login 401 (Unauthorized)

awx.api.generics Login failed for user admin from @my-IP
django.request Unauthorized: /api/login/
django.request Unauthorized: /api/login/
“POST /api/login/ HTTP/1.1” 401 5959 “https://my.custom.domain/” “Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/129.0.0.0 Safari/537.36” “192.168.176.71”
POST /api/login/ => generated 5959 bytes in 515 msecs (HTTP/1.1 401) 10 headers in 470 bytes (1 switches on core 0)

I am using admin user with password retrieved from -admin-password secret and decrypted

Here is the config of external postgres db

  postgres:
    enabled: true
    host: @IP
    port: PORT
    dbName: awx
    username: admin
    # for secret management, pass in the password independently of this file
    # at the command line, use --set AWX.postgres.password
    password: 'DB_PASS'
    sslmode: allow
    type: unmanaged

Any Idea of troobleshooting please ?
