Unable to render HTML. Unable to access URL. COM error 800c0019 in FACILITY_INTERNET. The drive cannot locate a specific area or track on the disk

Question

I am getting the above error message in production when trying to call the AddImageUrl section of ABCPdf (version 10). This started occurring yesterday just after midday my hosting provider assures me nothing has changed I am the only developer on the project as was working on something else entirely.

The URL provided in the stack trace can be accessed in IE on the web server without any error messages (including SSL). There is also a UAT environment on the same web server in which the PDF works, the UAT environment is identical in code and application pool settings, the only difference is the web address and database.

The HTML the PDF is calling can take a little time to come up on first load. Given that data is different I have increased the timeout from 15 seconds to 2 minutes.

I have arranged a reboot to see if that fixes it, but I have run out of things to check.

Edit: I did think of one further check, could I add the image of a page not on the site ( https://www.google.co.uk/ ), doing this resulted in the same error so it appears not to be a blocking issue on the worker process.

— Edit2: switched to the gecko engine and it is now working.

Answer 1

You can sometimes get this error if the web browser within Abcpdf cant access the URL.

On the webserver add the URLs directly to the local machine hosts file

C:\Windows\System32\drivers\etc\hosts

The entry should look something like this

127.0.0.1   example.com
