On the Workflow Server computer where you have the Workflow Web Services installed, please confirm that the URL for the web application directory is valid and when tested, reports that the connection is successful.

Next, go to the Forms configuration page and verify that the value used as the Workflow Server is valid. From the Forms Server computer, confirm that you can open a web browser and go to http://[Workflow Server Value]/workflow and see the Workflow Web Services page.

If further assistance is needed, please open a support case. Include screenshots of the above configurations as well.

Hi there,

Are you using SSL on workflow and Forms?

You can try trouble shooting with this http://answers.laserfiche.com/questions/87148/Workflow-Server--The-remote-server-returned-an-error-500

No,I am not using SSL in workflow and Forms.Is it mandatory to use SSL to trigger Workflow from Form?

Actually i need to save some fields data from the Laserfiche Forms to Database?Is it possible to do with the javascript?if possible,please send the sample code to insert the datas into database.

It's not mandatory to use SSL. To insert into database, you cannot use Javascript, you'll need the SQL activity in Workflow.

You can file a Support Case about the Workflow cannot connect issue.

Message: The remote server returned an error: (404) Not Found.

I think it might have communication issue between workflow server and forms.please guide me to resolve the issue.

Hi Alexander,

I found the issue with the Workflow server name given in the Configuration page without port number.

Thank you guys for your support.It worked for me :)
