2. A list of available plugins
3. Erorr message
4. Login in admin Configuration > Plugins (site_url/Admin/Plugin/List)
5. No modifications. Just downloaded and installed.
I was getting this error message after deplying my own source code, but it resulted in the same error, but with a different path. The code is trying to access a path that is not available and is probably the location of source code on a dev machine.
here is the error stack pertaining to OfficialFeedManager.cs
System.OperationCanceledException: The operation was canceled.
