Question

OSError: [Errno 10061] WSAECONNREFUSED

Command we are using to run ,

nameko run --config configuration/nameko.yml test 3000 &

nameko.yml file contains below configuration,

AMQP_URI: amqp://guest:guest@10.10.10.10:5672    
WEB_SERVER_ADDRESS: 10.10.10.10:5672

Operating system: Windows 10 (Python code) Linux (RabbitMQ server)

Please help us to solve this.

is your web server address really the same as your rabbitmq address? the web server address is where others browse to your server (so should be on the windows machine) — second, Oct 27 '17 at 18:10
If you are using rabbitmq check if you can access the management plugin via port :15672 also your webserver address must use a different port for your app to run — Evans M., Jun 13 '19 at 17:12

is it possible that a firewall is blocking incoming (on the rabbit server) or outgoing (from the windows server) connections?

can you e.g. telnet or otherwise verify that you can connect from the windows server to the linux server on the ipaddress and port in your config?
