Connection refused [Errno 111] when typing swift start command - openstack

When I type the swift stat command, this error appears:
HTTPConnectionPool(host='controller', port=8080): Max retries exceeded with url: /v1/AUTH_d17698cf7bbf4dcc8fc59ed6f7b48052 (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f1b0c2939a0>: Failed to establish a new connection: [Errno 111] Connection refused'))
And when I type this command to see if there's a listen on port 8080, nothing appears:
netstat -tanpu | grep ":8080"
and when I try to restart or start the swift service with service swift-proxy restart, an error appears:
Assertion failed on job for swift-proxy.service.

Are you using the BASE_URL variable in your RobotFramework scripts to retrieve the auto-evaluated base URL ?
Have a look at this example.
Because RobotFramework here seems to be trying opening a connection on 10.170.227.195:5555, which does not seem to correspond with https://toscatoolbox.orange.com/

Apache Atlas and Airflow Integration

I am trying to integrate an Apache Atlas instance I have running with Apache Airflow. Once I set up the connection in airflow.cfg I tried running a DAG from the Airflow scheduler. I get the following error in the log.
[2021-02-02 20:50:47,958] {connectionpool.py:752} WARNING - Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f464b856950>: Failed to establish a new connection: [Errno 111] Connection refused')': /api/atlas/v2/types/typedefs

My airflow.cfg is configured as the following:
[lineage]
backend = airflow.lineage.backend.atlas.AtlasBackend
[atlas]
username = <username>
password = <password>
host = localhost
port = 21000
I have tried changing the host to http://localhost as well. I am not sure where to investigate in Atlas to identify why the connection is being refused.
Connection Refused means either service is not listening on the configured port or the wrong hostname.
Try to replace localhost to fqdn,
A good way to configure it correctly is to access atlas ui and simply put the hostname from the url to config.
I was able to solve the problem by adding the --hostname flag when starting the docker container for atlas. I then used the hostname I provided as the host in airflow.cfg

Getting this error Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection

I am new to Oracle, installed oracle SQL developer but each time I try to connect, I get the error:
Status: Failure -Test failed: IO Error: The Network Adapter could not
establish the connection
and the oracleTNSlistener service turns off on its own. Each time I start the service, it turns off immediately on its own.
