Resolving The Problem
One possible reason you are receiving this error is that the web.xml and portlet.xml have not been correctly configured to point to the correct translator server URL or web server URL if a load balancer is being used.
It is important to note that PWSforwarder is a servlet that passes specific requests to the Webform Server framework so they can be processed. This means that the translatorLocation and logServerName parameters will need to point to the correct locations for PWSForwarder servlet found in the web.xml.

Note: The logServerName and logServerPort are no longer relevant in 4.x and should be removed from the web.xml and portlet.xml files.
