Symptoms

K2 designer for sharepoint unavailable in SP2010 farm after moving to SSL
 

Diagnoses

SSL is not required on K2 when using SSL in sharepoint 2010. The reasoning behind this is that as K2 installs components on the sharepoint machine's themselves, The majority of traffic between K2 and sharepoint communicates via API call, or TCP on ports 5555/5252 by default. The web designer in SP2010 is hosted inside sharepoint itself, so essentially enabling SSL for sharepoint enables SSL for the k2 designer for sharepoint.



 

Resolution

When checking event logs, we found entries referencing "MachineToApplication", which typically is a result of either the webdesigner folder or it's subfolder eventweb not being listed in IIS as an application. Running the K2 configuration from sharepoint 2010 resolves this. As the site was likely created by sharepoint and not K2, the directory structure and the application flag was not set by sharepoint.
