Time-out when calling Postcode webservice

Hi everyone!

I'm hoping to get your advice with the following problem:

We are calling the Postcode API (https://www.postcodeapi.nu/docs/v2/) from our test environment (on premise), it fails with the following error:

an error occurred while making a rest call to url https://postcode-api.apiwise.nl/v2/addresses/?postcode=6218AE&number=25 with api key MAJGuW6adh92f4aNKJ65e1aJHWugr58ZjeQJ8HBE

Locally, in the development environment, it works without problem. Seeing the above error, we suspect it has something to do with the proxy on the test verver.

We have entered the “-Dhttp.proxyHost=11.12.100.3  -Dhttp.proxyPort=8080” in the “extra JVM parameters” field in the Mendix console, but this does not fix the problem. Our network administrator tells us it has to be a Mendix configuration issue. No authentication or SSL certificate are required, and the machine that runs the mendix installation can connect to the internet via a browser without problem, using the same proxy information.

I see you can configure the proxy in the “call REST service” action in the modeler. However our application is not using those actions, but using Java actions from the app store "Restservices” (4.4.0) module. I would expect that adding the JVM parameter would make it work anyhow, without adding the proxy information in the modeler.

So my questions are:

 

Thanks!

Thank you for you replies!

I have done a quick ‘n dirty test, built a consuming webservice using native REST to connect to the Postcode API. This seems to work with the proxy settings, so my conclusion is that the problem is with the Restservices module from the appstore in combination with our application.

We will build a new postcode API in native REST!
