Hi,

I am developing a provider-hosted app which programmatically adds the app part on Home page of the site. I wrote the code for adding the app part in App Installed event. It works fine when i debug it on my development site. Then i made a catalog site and deployed it there following the instructions in this blog.

After deploying the app on app catalog, when i try to add the app, i get the following error.

I am deploying the app with non-system user. Is there any any limitation of using app installed event in app catalog or am i doing something wrong?

Hi,

The following blog for you to check:

SharePoint 2013 Domain Certificate for Provider-Host App Development Environment

http://rwcchen.blogspot.com/2013/12/sharepoint-2013-domain-certificate-for.html

Or try to add the following line within <system.net> tag in your SharePoint site web.config:

<settings>
<servicePointManager
checkCertificateName="false"
checkCertificateRevocationList="false"/>
</settings>

Best Regards
