You document the Trusted Application and Trusted Application Pool, remove and recreate it but the error still persists.
Solution
One of the things I noticed for this environment was that the ResKit was installed in the Microsoft Lync Server 2010ResKit directory so I initially reran the ResKit install (https://www.microsoft.com/en-us/download/details.aspx?id=36821) to see if it would upgrade it but the window I was presented with was to either repair or remove. I ended up choosing repair but this did not correct the issue. After not having any luck with other troubleshooting steps, I went ahead and uninstalled the 2010 tools and reinstalled into the Microsoft Lync Server 2013ResKit and this corrected the issue. It appears the ResKit installer does not identify whether the existing install was for 2010 or 2013.
The following is the successful output:
