Within our installation of Laserfiche Forms (we are running version 10.4.1), whenever we try to validate a process within any of our forms, any Workflow Service Task that is used in any form's Process Diagram comes up with the same error:

The workflow for the service task named "<Task Name>" returned back error: "The remote server returned an error: (404) Not Found."

This error is happening in spite of the fact that these workflows are being properly triggered and are running properly.  Further, no other tasks within a Process Diagram that are running properly are not throwing errors.

From a couple of other posts on Laserfiche Answers, I had a couple of suggestions:

1) Try visiting the Workflow server via the Web, and see if this resolves properly.
Using the URL http://<Workflow  server>/Workflow, I was able to access the home page of Workflow Web Services without any problems.

2) In Laserfiche Forms Configuration, under Laserfiche, try turning off "Use SSL connection" under Laserfiche Workflow / Laserfiche Workflow Server.
I tried doing this as well, and this also had no effect on this validation issue happening.

It's a little bit puzzling why it's only happening only within this one function, however as mentioned, we have been able to ignore it and continue, but it *is* a bit of a nuisance.

Thanks in advance to anyone who might be able to assist with this!
