Any ideas on where to look? Both forms are on the same server.

Thanks,

Hi Michael,

Are there any themes or custom CSS/JavaScript in use with the problematic forms that are not in use with the form that works? If so, if you comment out the code, does the form behave as expected?

This error can occur if there is a reference to an external resource which is not resolving correctly.

Hope this helps!

I had the same error and found the Windows Firewall was enabled.

We recently set up our an external forms server on a DMZ. We've run into several problems, one of which is the same issue as for this post, in that a submitted form won't Email, Print or Download. An XML View of the error in Event Viewer/LFForms shows the following:

- <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">

- <System>

<Channel>LFForms</Channel>

<Computer>LF-WebServer</Computer>

</System>

- <EventData>

<Data>Laserfiche Forms was unable to generate a PDF or TIFF. Contact your Laserfiche administrator for more information. Function: Error</Data>

</EventData>

</Event>

I removed the custom CSS to see if this was the cause, but that didn't help. There's no associated JavaScript with this form.

Edit: I was able to resolve this as well by using the Hosting Laserfiche Forms 10 In A Perimeter Network (DMZ) whitepaper.

Ran into a similar issue: The PDF generator was unable to contact the Laserfiche Forms server. Please ensure your SSL settings are correct. [LFF4112-PdfNetworkError]

Our issue was resolved by removing the hostname from the SSL binding in IIS.

Michael, what was the root cause of your item?

Carl,

If memory serves, it had to do with disabling settings on the DMZ Forms server so that they could be handled on our internal Forms server. Specifically this section from the White Paper referenced above:

Open the Windows Services Microsoft Management Console (MMC) snap-in
a. View the properties of the Laserfiche Forms Routing Service to Stop the service and change the Startup type to Disabled.
b. View the properties of the Laserfiche Notification Hub Service to Stop the service and change the startup type to Disabled.
c. View the properties of the Laserfiche Notification Master Service to Stop the service and change the startup type to Disabled.

Thanks,

Michael

@████████can you explain what you did with the IIS? I am having this same error message and not having any luck diagnosing it.

Thanks

@████████

We had a value filled in for host name. It was removed to broaden access to the SSL binding.

Hope this helps, it seems this issue is caused by a variety of things but center around network connectivity.

Cheers,

Carl

I had this error and found that forms was trying to resolve itself via the configuration for the Primary Forms URL, which is the external domain name. This was being blocked by a loopback protocol on the router.
