Timeout when reading response headers from daemon process 'mistral-api':

[sonshagithub]

Hello
I am doing tacker integration with openstack. Not able to create a VM.

[root@localhost devstack]# openstack vim list
+--------------------------------------+----------+----------------------------------+-----------+------------+---------+
| ID | Name | Tenant_id | Type | Is Default | Status |
+--------------------------------------+----------+----------------------------------+-----------+------------+---------+

+--------------------------------------+----------+----------------------------------+-----------+------------+---------+

STATUS ALWAYS REMAINS PENDING.

I am facing this issue. Please suggest

This is from the mistral-api.log
