Hi,
I would try a couple of things (I’m assuming this is for K2 for SharePoint 2013 app):
-Is this behavior consistent in a different browser (i.e. Chrome)?
-Please try adding the the smartforms site, SharePoint site and SharePoint apps site to the Trusted Sites in IE and see if that would help (Internet Options > Security > Trust Sites).
-Perhaps, the app store is not setup correctly. I would attempt to ping the app domain url from K2 server. You can also check if there is a problem with another app on the same site collection (get a free app from SharePoint store is usually what I would do).
Appreciate for quick reply.
We have tried mentioned possibilities but none of them worked in our case.
After doing the above mentioned options getting the error "This page can’t be displayed" and redirected to below one. ( like (slash)Runtime (slash)_trust/ (slash)pauthorize(dot)aspx")
