Error calling external webservice in nav 2018

dsrdev

Hi all,

I am calling an external webservice from NAV with dotnet. I am using the same code in dynamics nav 2016 as in dynamics nav 2018, while in 2016 it's working nicely in 2018 it's giving me the following error:

A connection attempt failed because the connected party did not properly respond after a period of time, or established
connection failed because connected host has failed to respond

This error happens in the following line:

RequestStr := HttpWebRequest.GetRequestStream;


Apparently, it seems it's somtehing realted to dynamics nav 2018 but I can't find what it is, I will be very gratefull if someone could help me with any idea or tip to solve it.


The code:

I have solved it: it was an error with the port I was using for the comunication.

Hi
I've got the same error, what do you mean by :
it was an error with the port I was using for the comunication?
where do you setup this port?

I believe if your IP is accessible from outside then its fine, How come Port Issue for this??

If I send my xml throught SoapUI, the connection is fine.
The error is only when I use
I do find why it doesn't work anymore?
It was fine before NAV 2018, in NAV 2017

500 means its unable to connect and it may have several reasons -
