Hello Demis According to the traceback given (highlighted below), it looks like there is an issue with your nginx config. You can manually run `sudo nginx -t` command on your proxy/nginx machine to see what the issue is. > [@demis08](#): > > ```auto > [172.19.3.41] sudo: nginx -t > [172.19.3.41] out: nginx: [emerg] no servers are inside upstream in /etc/nginx/sites-enabled/echis_commcare:29 > [172.19.3.41] out: nginx: configuration file /etc/nginx/nginx.conf test failed > [172.19.3.41] out: > > ``` ---

Hi Sravan, yes, the nginx test failed due to the change made by `fab restart service`. it comments on the `server 172.19.3.38:8181;` as shown below > upstream echis\_formplayer { > zone echis\_formplayer 256k; > > ``` > hash $cookie_formplayer_session$http_x_formplayer_session consistent; > > ``` > > #server 172.19.3.38:8181; > } ---

If you have manually edited the nginx, please make sure you haven't broken the configuration. If you want to rollback to normal, you can do `cchq ap deploy_proxy.yml` ---

Hi Sravan, the Nginx configuration is not edited manually, and `cchq ap deploy_proxy.yml ` task works properly. The issue every time I run the script ` fab restart_services` , it tries to edit the nginx config and completes with the above error. ---

hello @Sravan_Reddy and @CharlSmit recently found that the error is not related to the fab script. it's related to 'users` on a single host. I created a new post here: [Getting an error on bootstrap-users](https://forum.dimagi.com/t/getting-an-error-on-bootstrap-users/9312)
