500 Internal Server Error

WebLink

We are getting 500 Internal Server Error when trying to Download a PDF out of Weblink. However this error only occurs when accessing Weblink from outside their network (they have a public facing Weblink). Doing it from inside the network works just fine. We have tested on the same document and also tested as the same Weblink user. The same Weblink user works inside but not outside so it does not seem to be the security credentials. It would seem the ports are fine as we can get to the document and see things, only when we try to download a PDF. Is there another place we can look for a more detailed error message?

There should be more information in the event viewer of the server machine. If I had to guess at a problem, it might be that the application pool user doesn't have write rights to the pdf temp folder (which you would address by giving rights to the IIS_IUSRS group). For internal users, the requests might be using Windows authentication and impersonating the caller while writing.

I'm running into the same error with Weblink. Can someone please confirm that by adding the Modify rights to the IIS_IUSRS group on the PDFtemp folder would resolve the issue? Do we need to restart any services? thanks!

Hi, we have a customer that has the error when trying to print the PDF internally. We traced the PDFtemp folder location and gave the IIS_IUSRS group the modify rights to that folder, but the customer still has the issue. Didn't really see anything odd in the Events Viewer on the Weblink server or on the customers PC. Any ideas?

Issue resolved! Turns out we were missing some handler mappings that were from the VenderLink_Supplier site. Had to compare the mappings from the VendorLink site to determine the difference, and then manually create the missing mappings in the Venderlink_Supplier site.
