cfhtmltopdf connection refused?

[tonym64063353]

We migrated our Coldfusion 2023 Windows Server to a new server over the weekend, and "cfhtmltopdf" has stopped working.  It can generate a PDF fine and display it, but when actually trying to save it to the server, we get this:

<cfhtmltopdf

destination="c:\filename.pdf"

  source="http://#CGI.Server_Name#/filename.html" overwrite="true">

</cfhtmltopdf>

Jan 31, 2024 13:16:12 PM Error [ajp-nio-127.0.0.1-8022-exec-24] - Connect to 127.0.0.1:8995 [/127.0.0.1] failed: Connection refused: connect http://127.0.0.1:8995/PDFgServlet/

Jan 31, 2024 13:16:12 PM Error [ajp-nio-127.0.0.1-8022-exec-24] - Error occurred while generating PDF.

Not sure if this helps, but http://127.0.0.1:8995/PDFgServlet/ brings up:

HTTP ERROR 400 Bad Request

URI: /PDFgServlet/

STATUS: 400

MESSAGE: Bad Request

SERVLET: PDFgServlet

Powered by Jetty:// 9.4.51.v20230217

The service for Coldfusion2023add-onservice is running, and port 8995 is open.  

Any ideas/suggestions?

The HTTP 400 error suggests that ColdFusion can actually connect with the PDF service. This is confirmed because ColdFusion can generate and display PDFs.

You are perhaps getting the error because cfhtmltopdf is unable to read a file or to overwrite an existing PDF. The source file may not exist .  Is the source paerhaps http://#CGI.Server_Name#:#CGI.Server_Port#/filename.html ? The destination PDF file may be open or be locked by another process. Check that.
