Cannot perform any view outside the lan 2.18.3

[Ricardo Tolivia]

Hi everyone, here is the deal. I have all running inside the lan, i can access from every pc via browser, oviyam, weasis latest versions installed works, no errors.

The problem comes when i try to open any viewer outside the network via "mydomain:8080", if i go to "mydomain:8080/dcm4che-web3" it show the list of studies, and i can preview the images, but when i click the EYE buttom to go to weasis, the jnlp download never starts, and the server throws this error:

Check your weasis-pacs-connector.properties settings for pacs.aet, pacs.host and pacs.port.

I didnt change anything there, the values are:

##########  PACS properties ########## 

# AET, hostname and port of the PACS

pacs.aet=DCM4CHEE

pacs.host=localhost

pacs.port=11112

[Nicolas Roduit]

There is a connection refused on http://domain:8080/weasis-pacs-connector/viewer

Do you have a firewall that blocking this URL?

[Alexandr Kuznetsov]

Hi everyone!

I have the same problem as Ricardo Tolivia. dcm4chee 2.18.3 works fine in the local network. Weasis 3.5.4 loads and displays the pictures. When I go from the Internet to the local network, the Weasis does not load, instead another browser window opens. To connect to a computer on a local network, I use port 8080 forwarding. The firewall is turned off.

In the logs, I see when the local network and the viewer are loading:

-------------------

When I connect to the server through OpenVPN, there are no problems either. But this forces all users to have OpenVPN, which is not always convenient.
Probably not enough port forwarding of 8080 and 11112?
I can’t solve this problem in any way. I ask the help of the community.
Thanks .

First, it is not recommended to use version 2.18.3 outside a local network for security reasons (vulnerable to several known attacks).

The problem is probably due to a proxy server configuration (at Java level) or a firewall restriction.

[Zilvinas Nedelcenka]

Hello,

please tell us how do you solved this problem - I have the same problem today...

Thank you very much!

Best regards,

Zilvinas

[Alexandr Kuznetsov]

The problem is not resolved as described.

The only solution when there is security and loading the viewer for me is using OpenVPN. Then the server and the client are in the same secure LAN and there are no port forwarding. And I keep using it.

Best regards,

Alexandr

it sounds like a NAT issue. But in that case many, if not all, installations should work well only locally. I wonder how many people have this problem

[Nicolas Roduit]

dcm4chee 2.18.3 is obsolete and has not been updated for several years and will not be updated again. It is strongly discouraged to use this version outside of a protected local network. 

[Nicolas Martino]

This is too old, but I had the same problem because I run dcm4chee 2.18.3 in a docker environment and I want to access it from another network (not from internet, but it's the same case ).

I handled this by setting up a reverse proxy and exposing it to access the dcm4chee 2.18.3 backend server

Notes:

 -  I configured weasis-pacs-connector to use Weasis Protocol.

-  As @Roduit says it is strongly discouraged to use this version outside of a protected local network

You must change <IP> according to your dcm4chee server, the nginx configuration is:

upstream dcm4chee {
    server <IP>:8080;
}

server {
    listen 80;

    location / {
        return 301 /dcm4chee-web3;
    }

    location /weasis-pacs-connector {
        proxy_buffering off;
        proxy_pass  http://dcm4chee/weasis-pacs-connector;
        proxy_set_header Host $host;
    }

    location /wado {
        proxy_buffering off;
        proxy_pass  http://dcm4chee/wado;
        proxy_set_header Host $host;
    }

    location /dcm4chee-web3 {
        proxy_buffering off;
        proxy_redirect off;
        proxy_pass  http://dcm4chee/dcm4chee-web3;
        proxy_set_header Host $host;
    }
}
