Error 111: Connection refused

[Vahid]

Hi

i installed latest version of taiga back-front on my ubuntu server (16.04) in production environment and it have this error on nginx.error file Repeatedly:

2018/03/25 07:33:18 [error] 1726#1726: *1660 connect() failed (111: Connection refused) while connecting to upstream, client: x.x.x.185, server: mydomain.com, request: "GET /events HTTP/1.1", upstream: "http://127.0.0.1:8888/events", host: "mydomain.com"

whats cause of this error and how can i solve it?

[David Barragán]

This is a "waning" error because taiga-front is configured to connect to a taiga-event instance but it can't. This cause than you will not have real time updates in your kanabn/taskboard panel, that's all. You can ignore this message or set an empty value to the event server url in the config file if you don't need real time or setup a taiga-event instance.

Regards.

Hi

Thank you for answer.

I had installed Taiga-Event according bellow guide :

https://taigaio.github.io/taiga-doc/dist/setup-production.html#taiga-events

so according this error there is a problem with Taiga events

this is output of "service circusd status" command:

also version of node and npm:

admin@studio:/home/taiga/taiga-events$ npm -v
5.6.0

admin@studio:/home/taiga/taiga-events$ node -v
v8.10.0

is there any other thing which i can give you to help solve this issue too?

[David Barragán]

Use

circusctl status  

to show the status of the diferent circus watchers (for back, front, event...) 

You could try to run taiga-events front the terminal directly to show if there is any error (cd taiga-events && node /usr/local/bin/coffee index.coffee) or try to see the log files.

 

Maybe it could be a problem with the proxy pass setting in the nginx configuration.

Maybe taiga-front config file is wrong.

Taiga can't conect with your SMTP server ([Errno 111] Connection refused).

You should check the email settings in settings/local.py.
