Update feed could not be connected #16

Closed akhilchandra closed 8 years ago

akhilchandra commented 8 years ago

Hi micwallace,

Installation went fine. Read through all issues and was able to get it working. All good, thanks...

However, when I login on POS or admin/#!realtime, the browser throws an error "Could not connect to update feed"

IN the logs, I see this request being sent

https:// www.domainname.com /socket.io/1/?t=1452453610089

Browser Console Log: Shows a status of "400: Bad Request" as response. I think its a JSON parse error( as shown in firefox browser console.

If I open the link directly in browser, in return I get "{"code":0,"message":"Transport unknown"}"

Any help appreciated ..

Regards, Akhil

Hi Akhil,

Looks like you need to configure a domain for your app instance. Seems like you are accessing it via IP address?

Cheers, Michael

Hi Michael,

I am accessing it via domain name, not via IP address. Is there any place to configure a domain within the POS?

Regards, Akhil

micwallace commented 8 years ago

No it's all done via apache virtual host "server name" value.

Yes, the apache virtual host setting has "ServerName" set to < domain name > .. No IP's used ... Still the issue exists.

I am using nodejs version v4.2.4 and installed socket.io using " npm install socket.io "

micwallace commented 8 years ago

https:///socketio/ is a strange request. Where is the domain? Did you remove it?

Make sure the node.js feed server is running.

Can you provide your apache virtual host config and error log?

May be the domainname got deleted when I posted or hidden due to security. The domain name is there in the URL

Node.js feed server is running. Here is an extract from netstat tcp 0 0 127.0.0.1:8080 0.0.0.0:* LISTEN 6119/node

Apache virtual host config( I am replacing domain name with <domain name here> )

<VirtualHost *:443>
         DocumentRoot /var/www/html
         ServerName <**domain name here**>

            AllowOverride all
         </Directory>

         # WSPROXY CONF

         ProxyPreserveHost On
         <Proxy *>
                 Order deny,allow
                 Allow from all
         </Proxy>
         ProxyPass /socket.io/1/websocket/ ws://localhost:8080/socket.io/1/websocket/
         ProxyPassReverse /socket.io/1/websocket/ ws://localhost:8080/socket.io/1/websocket
         ProxyPass /socket.io/ http://localhost:8080/socket.io/

                 Order allow,deny
                 Allow from all
         </Location>
    </VirtualHost>

There is no error with the request. I see the 400 Bad Request on the access.log file, when I log in either at pos or at admin level. Again, I am replacing domain name with <domain name here>

What versions of apache and socket.io are you using?

Looks like the endpoint may have changed in newer versions: https://github.com/socketio/socket.io/issues/1696

Make sure you have version 0.9.17
