I have the following scenario:
server: Ubuntu 20.04.3 LTS
openstack installed with devstack
watcher 2.2.0
Every services seem to be working and i can see the watcher dashboard on localhost.
But I think I have an auth problem between watcher and keystone :
Error contacting Watcher server: Unable to establish connection
to http://x.x.x.x:9322/v1/services: HTTPConnectionPool(host='x.x.x.x', port=9322):
Max retries exceeded with url: /v1/services (Caused by NewConnectionError('<urllib3.connection.
HTTP Connection object at 0x7fba33b1be50>: Failed to establish a new connection: [Errno 111] Connexion refusée')).
Attempt 6 of 6
I'm testing something on a VM, I put the same IP and the same password everywhere
Where should I look first ?

I installed Openstack in Ubuntu and started it using the ./start.sh command. When I try to login the dashboard, I get the error below about not being able to connect to Neuron:
ConnectionFailed at /project/
Connection to neutron failed: HTTPConnectionPool(host='192.168.204.173', port=9696): Max retries exceeded with url: /networking/v2.0/extensions (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f7efde4f460>: Failed to establish a new connection: [Errno 111] Connection refused'))
How do I fix this?
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
I make a server and request successfully in windows,then I put them to the linux which is the develop machine of company.
And I Got Connect Failed error when I run the clien.py. I have changed the host IP to localhost,0.0.0.0,127.0.0.1 and the IP of develop machine,but it doesn't work.
And I tried the docker inspect command,but the IPAddress is empty like "".
And I changed the port to 8500,8501,4321 and still got the error.
I tried make proxy to the company,the request returns a Name resolution failure error.So I think maybe the cause is the net of company?
Any answer would be very appreciate!

I followed https://www.theurbanpenguin.com/installing-devstack-on-ubuntu-16-04/ tutorial to install devstack(queens release) on my Ubuntu 16.04 server.
After the installation was done I ran the following commands
export OS_USERNAME=admin
export OS_TENANT_NAME=admin
export OS_PASSWORD=<password>
export OS_AUTH_URL=http://server-ip:5000/v2.0
openstack image create --public --disk-format qcow2 --container-format bare --file /home/cse3/ubuntu_images/ubuntu-14.04-server-cloudimg-amd64-disk1.img ubuntu
But whenever I open http://server-ip:5000/v2.0 in my browser I am getting unable to connect error.
When I create an image from the command line I get the following message
Failed to discover available identity versions when contacting http://server-ip:5000/v2.0. Attempting to parse version from URL.
Unable to establish connection to http://server-ip:5000/v2.0/tokens: HTTPConnectionPool(host='server-ip', port=5000): Max retries exceeded with url: /v2.0/tokens (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f84ebecabd0>: Failed to establish a new connection: [Errno 111] Connection refused',))
Can anyone suggest what steps need to be followed to remove this error?
After installing the Devstack, you should be able to view the OpenStack dashboard at http://server-ip if the server-ip is a public IP. The AUTH_URL is for you to authorize the API when you are using the SDK or the client library. And this is actually how the dashboard (Horizon) works with the Keystone identity service.
If the server_ip is not a public IP, you need to set up a proxy port in your server and your browser.
It's because the identity API changed from
export OS_AUTH_URL=http://server-ip:5000/v2.0
to
export OS_AUTH_URL=http://server-ip/identity
You can get more from the OpenStack Doc
Check your httpd is running
systemctl status httpd
If it is exited or not started .
Enable the httpd
systemctk s
Just getting started with OpenStack.
got everything set up on a Ubuntu VM (under Parallels).
When I attempt to log into the browser console as admin (the password was set during the DevStack install) - I get:
HTTPConnectionPool(host='10.211.55.16', port=8774): Max retries exceeded with url: /v2/a586870bde4c4dfc993dc40cab8047b7/extensions (Caused by <class 'socket.error'>: [Errno 111] Connection refused)
I am however able to run CLI commands such as keystone-tenant-list, and all others, on the actual server.
I made sure that I'm able to ping the virtual Ubuntu host from my Mac. When I first enter http://myhost.mydomain I do get a login page, but, as soon as I enter admin's credentials - I get this ugly (and super long error)
What things could I check to fix this?
Resolution:
1) Wiped clean my Ubuntu host
2) Followed set-by-step instructions here: http://www.stackgeek.com/guides/gettingstarted.html
Everything now works without a glitch.
