Symptoms

When trying to Register the K2 for SharePoint App on the Site Collection under the PWA site (Project Webb)collection. the registration wizard fails on the last step.
 

Diagnoses

We noticed the the PWA site instance name was PWA and the web Application the instance based on was named rwa.xxx.xxx.com.
Using this a the same name as what the webApp caused the issue.

 

Resolution


This is currently not supported, as this type of site has not been tested by QA.
Thus a fix could not be released for the client.
Workaround is to create another instance and use a different name.
