Cannot access Dynamics XRM from within Event Receiver

Question

Hello everyone
I'm struggling with an issue here and I would like to hear some advice from you. The problem is the following:
I need to do something on Dynamics CRM whenever a document is uploaded to a specific location in SharePoint. I'm using an Event receiver for this purpose and connecting to CRM via the IOrganizationService, like this:
IOrganizationService service = new OrganizationServiceProxy(serviceUri, null, credentials, null); //service uri is https//serviceUri is something like "https://crmserver/organization/XRMServices/2011/Organization.svc"
But for some reason I'm unable to execute that line successfully (looks like it times out) from within the Event receiver. However, the same exact piece of code works perfectly fine if executed from a separate console application (i.e., outside the IIS application
pool) running on the same SharePoint server...I'm confused, do I need to configure anything else on the SharePoint application pool so it let's me access the XRM service?
More info:
- It's not credentials issue, even provinding hardcoded it doesn't work
- Both SharePoint 2013 and Dynamics CRM 2013 are on premises.
- Integration between SharePoint and Dynamics CRM is done through the CRM List Component, over https, and it's working fine.This is not really important for this but it's just to tell that both servers can comunicate over https.
I would really like to get some advice on this. Thank you in advance.
Regards

Hi,
Per my understanding, there is an issue when trying to access Dynamic CRM in an Event Receiver.
As you said, the same code works in a Console Application, it means the code should be OK. To narrow down the issue, I suggest you do as follows:
1. Please debug this Event Receiver in Visual Studio to see if the Event Receiver is working, what’s more, it will give you more information about how the code works
or if there is any exception thrown during debugging;
2. Is it a Sandboxed solution? Sometimes
the limitation of a Sandboxed solution would interrupt the code execution, you can try to change it to “Farm” solution and make another test;
3. If the above steps not work for you, please trace the requests using Fiddler when the Event Receiver running, more details there would help you easier to find out
the root cause of this issue.
