Could not connect to Server client error

[Adrian Herrera Montenegro]

Hi all

I installed trytond 4.5 in Ubuntu 12.04.5 and apparently I initialized correctly the PostgreSQL database because I ran the following command successfully:

trytond-admin -c tryton.config -d tryton --all

This is what I have in my tryton.config file:

[database]

uri=postgresql;//tryton:try...@127.0.0.1

Then I started the server:

trytond -c etc/trytond.config -v

output:

5078 -1216570624 [2017-05-11 17:39:53,993] INFO trytond.config using etc/trytond.config as configuration files

According to the last line, it is running in the port 8000.

I tried to connect with Tryton client v 4.4 installed in Windows 10 in a different computer but in the same network, but when I go to the Profile Editor,and try to connect to the server, I got a Could not connect to Server error message.

I have seen some older posts that describe the same scneario and same error, but I see they have a different output line when they start the service, they have something like this

[Wed May 21 13:28:02 2014] INFO:server:starting JSON-RPC protocol on *:8000

so, I don't have that JSON-RPC in my output, but I have the wekzeug * Running on http://localhost:8000/ output instead

If you have any idea what I can do to solve this, would be much appreciated,

Regards,

Adrian

You must use the same series between the client and the server.
For the client 4.4, you must have a server 4.4.
Also version 4.5 of the server is the development branch, it is always
changing.

For newer versions (Since 4.0 IIRC) you have yo use

[web]
listen=0.0.0.0:8000

To make the server listen on all interfaces. Otherwise you will only be
able to connect from the same machine, as trytond by default only
listens to localhost.

I'm not trying to connect via web, I'm trying to connect from Tryton client installed in a different machine, although I'm testing via web just to make sure the server is reachable

One of the things I noticed is that I'm able to Telnet demo4.4.tryton.org, so I tried to Telnet my Tryton server instance without positive results, but that points that something is blocking the traffic from the server itself, I thought it was the firewall, so I deactivated ufw, but still I'm unable to connect.

I keep working on this trying different thins like trying to connect via web from the local machine, here is were I got hope, the server responded with a 400 error code. Now I'm going to try to connect from local instance of Tryton client, if the result is positive, I will work on the thing that is preventing a remote machine to connect to the server.

This doesn't matter you have to apply the same configuration no mather
if you use gtk client or web client.

As I explained before, that's because your server only listens to local
interface, so you are not able to connect from other machines. Changing
the configuration as already told will solve the issue.
