After updating CF2023 to update 13, htmltopdf stopped working. I implemented the workaround as documented on the update 13 release note. The log shows that the PDFgServlet is registered, but now in the log all I see is "Error occurred while generating PDF." when I try to generate a pdf. I'm on Win Server, IIS and CF2023. I've included the code that I used to test as well.

cfhtmltopdf(

source = "https://www.google.com/", destination = "sample.pdf", overwrite = true ); May 2, 2025 113436 AM Information [ajp-nio-127.0.0.1-8122-exec-3] - PDFg service manager http://127.0.0.1:8995/PDFgServlet/ registered. May 2, 2025 113852 AM Error [ajp-nio-127.0.0.1-8122-exec-5] - Error occurred while generating PDF.

"ColdFusion has introduced IP-based filtering on the Jetty side. View cfhtmltopdf for more information." That's probably the issue.

I've added that file to jetty as well and allowed the localhost as well as the IP for the server. \cfusion\jetty\etc\jetty-ipaccess.xml
