Accessing /admin throws Site matching query does not exist

[Juanito]

Hi,

I try to access django admin but when I do it gives me "there has been a 500 error..."

I have LMS, CMS running on one server, and mysql on another server.  

/edx/var/log/lms/edx.log

outputs: DoesNotExist: Site matching query does not exist.

Apr  6 19:43:46 ip-172-16-1-10 [service_variant=lms][django.request][env:sandbox] ERROR [ip-172-16-1-10  31979] [base.py:256] - Internal Server Error: /admin/login/

I check select * from django_site and I see an entry there domain = example.com, name = example.com

Anyone have experienced this?

Thanks

I have been experiencing this on devstack lately, and have found that it only happens if I am not logged in. If I login to the LMS first, then access the django admin, it works fine.
