Last post not solved, same issue "postgres.railway.internal" to address: Name or service not known

Question

`django.db.utils.OperationalError: could not translate host name "postgres.railway.internal" to address: Name or service not known`

Struggling with the above error trying to run `railway run python manage.py createsuperuser` on my project.

I can share whatever is needed to assist with helping me get this to work on my local machine.
