I have observed TLS/SSL secure channel issue with provide hosted app while testing the application(XLCubedViewer). The issue is occurring due to disabling of the TLS 1.0.
"error is: at System.Net.HttpWebRequest.GetResponse() at Microsoft.SharePoint.Client.SPWebRequestExecutor.Execute() at Microsoft.SharePoint.Client.ClientRequest.ExecuteQueryToServer(ChunkStringBuilder sb) at Henkel.XLCubedReportsWeb.Controllers.HomeController.GetDefaultImageLinkUrl(String tileID)
The underlying connection was closed: An unexpected error occurred on a send"
Is there any out of the box solution (without any application code change) which can tell application to connect to the default TLS protocol???
