Admin and MinIO UI not opening in On-Premises (Without DNS) Deployment

Hello MOSIP Team,
I have successfully installed MOSIP v1.2.0.2 (On-Premises Without DNS) and completed deployment of 24 microservices.
Status
All pods are running properly:
Admin Namespace:

admin-hotlist Running
admin-proxy Running
admin-service Running
admin-ui RunningMinIO Namespace:

minio RunningRegistration Client UI is working:

https://regclient.sandbox.mosipdemo.net :x: Issue
Admin and MinIO UIs are not opening:

https://admin.sandbox.mosipdemo.net

→ 404 Error

Query
Since all pods are running and I am following On-Premises Without DNS setup, why are Admin and MinIO UIs not opening?
Is there any missing configuration?
Kindly guide me.
Thank you.
