proxyserver problem

[PeterDorsman]

Dear warrieka,

We aren't able to retrieve any information from web services with the use of the plug-in on our company network. My ICT-department told me this is because we use a proxy server for the communication with the internet.

I hope you are able to fix this.

If you need more information please let me know.

Below here an example of when I ask for information from a wfs webserver. This gives the following error:
