Fixed: SharePoint Designer Error - Unexpected error on server associating the workflow

How ever if you try 5-6 times, you might end up publishing it. But sometimes it won’t work.

But there’s a work around to fix the above issue.

Open the ‘web.config’ which associate with the site collection that you are publishing the workflow.
(E.g: ‘C:\inetpub\wwwroot\wss\VirtualDirectories\<Port>’)

Find the following entry :

<httpRuntime maxRequestLength="51200" />

And change it to :

<httpRuntime maxRequestLength="51200" executionTimeout="300" />

Save the ‘web.config’ file and restart the web site from IIS.

Now you can publish the workflow without any issue.
