The error shows we're now ready for the final sprint to the line. I say this because I think the cause of the error is that the port number 8993 is incorrect.
In a recent thread on PDF generation I showed a way to find the correct port programmatically. I shall repeat it here.
Save the following code as a CFM page and launch it:
<!--- Execution time of code = approximately 6 seconds on ColdFusion 2023 --->
<cfset pdfServicePort="">
<cfloop index="port" from="8985" to="9005">
<!--- Domain of PDF Servive Manager is 127.0.0.1 --->
<cfhttp url="http://127.0.0.1:#port#" method="get" result="cfhttpResult">
<cfif not findNoCase("Connection Failure",cfhttpResult.fileContent)>
<cfif structKeyExists(cfhttpResult.responseHeader, "server") and findNoCase("Jetty",cfhttpResult.responseHeader.server)>
<cfset pdfServicePort=port>
<cfbreak>
</cfif>
</cfif>
</cfloop>
PDF Service port: <cfoutput>#pdfServicePort#</cfoutput>When I run this code I get port 8996. Yours might be different.
Once you have the port number, implement it as follows:
- Open the ColdFusion Administrator and go to Data & Services > PDF Service.
- Click on the button to edit the PDF Service Manager.
- An editing form appears. Enter the port number that you obtained from the code:
- Press the button Update PDF Service Manager, followed by the button Verify All Service Managers.
- "OK" should appear as the Connection Status.
- Now, run your cfhtmltopdf code.
And lo and behold! When it try cfdocument in our wwwroot that doesn't use SSL, I get:
Using cfhtmltopdf still produces a server error.
Also, running PDF port code here produces Connect Exception: Connect to 127.0.0.1:9005 [/127.0.0.1] failed: Connection refused: connect
I have to say that I've never had this much problems with a single update, and I've been using CF since MX 7.
If I tun this, I get nothing as service port. Then I checked with cfdump var="#cfhttpResult.Errordetail#",
and I get: Connect Exception: Connect to 127.0.0.1:9005 [/127.0.0.1] failed: Connection refused: connect

The Connection-Refused is not an issue. It is to be expected. The code should produce that when it cannot make a connection for any port in the range 8985 to 9005.
The relevant result is the fact that the code could not find any port. The question I now have is whether the PDF service was running at all. It does not normally require a certificate.
Let us rule something out: whether or not you can "verify" the PDF service.
Open the ColdFusion Administrator of the specific instance. Go to Data & Services > PDF Service.
From what you have said, you should see that the PDF Service Manager is registered with port 8993. Can you confirm this?
Next, press the button Verify All Service Managers. What happens? What is the Connection Status?
Connection status is "Error", and manager can't be started.

Thank you. That is important to know.
That is in fact the kind of feedback I am missing from you. Feedback such as "not working" and "I get an error" and "getting weird now" won't bring us closer to the solution. At this stage, what I consider the most important of my questions are those about the steps you do, and the result.
- Did you follow the steps I gave earlier to download and install the Add-On Service for ColdFusion 2021.?
If so, what happened at every step? - Did you follow the 10 steps I gave about using cfpm.bat?
If so, what happened at every step? - Did you open the ColdFusion Administrator of the instance, go to the Package Manager page. and click on Available Packages?
If so, were there any (available) packages there? If so, which packages?
If there were packages there, what happened when you clicked on each, then on Install ?
This happens on the problematic server when running install all:
zip package cannot be installed by the server. Please check the server logs and try installing again.
ajax package cannot be installed by the server. Please check the server logs and try installing again.
Other test server didn't produce any errors with install all

This is not directly related to the cfhtmltopdf problem. Nevertheless, we're almost there.
Next, restart the ColdFusion instance.
Open the ColdFusion Administrator of the instance. Go to the Package Manager page. Click on Available Packages.
Do you see Ajax and Zip buttons there? If so, click on each, then on Install.
