Obtaining a run time error, depending on the URL.

[Former Member]

Hi gurus,

Our portal server has 2 different URLs. One of them is within the LAN or VPN, and the other is for external use, especifically for our providers.

The current problem is a run time error, that only occurs while providers acces from external URL. However, While we acces with same data within the vpn, application works flawlessly.

the error captured is the following. :

Hi Jose, can you elaborate a little more on how did you manage to have 2 different URL for your portal?

Also, I see that the error occurs on calling the method ExportPDF, are you using an Adobe Document Services? Is it in a different server than the portal? If that occurs then maybe the external user is able to access the portal but not the ADS and that would be causing the error.

Regards.
