Unable to connect debugger to cloud slot

Hi all, I tried to connect my debugger to an app in a mendix cloud slot today and get the following error message: The request was aborted: Could not create SSL/TLS secure channel System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel. at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context) at System.Net.HttpWebRequest.GetRequestStream() at Mendix.Modeler.Microflows.Debugger.DebuggerClient.DoHttpRequest(String url, String password, String userAgent, String json, Int32 timeout) in C:\jenkins\workspace\Modeler-Build-6\modeler\Mendix.Modeler.Core\Microflows\Debugger\DebuggerClient.cs:line 197 at Mendix.Modeler.Microflows.Debugger.DebuggerClient.PerformRequest(DebuggerRequest request, Int32 timeout) in C:\jenkins\workspace\Modeler-Build-6\modeler\Mendix.Modeler.Core\Microflows\Debugger\DebuggerClient.cs:line 163 at Mendix.Modeler.Microflows.Debugger.DebuggerClient.StartSession(IEnumerable`1 breakpoints) in C:\jenkins\workspace\Modeler-Build-6\modeler\Mendix.Modeler.Core\Microflows\Debugger\DebuggerClient.cs:line 64 at Mendix.Modeler.Microflows.Debugger.DebuggerController.StartDebugging(String url, String password, ConnectionMode mode) in C:\jenkins\workspace\Modeler-Build-6\modeler\Mendix.Modeler.Core\Microflows\Debugger\DebuggerController.cs:line 95 at Mendix.Modeler.Utility.BackgroundUtil.<>c__DisplayClass1_0`1.<Do>b__0(Object s, DoWorkEventArgs e) in C:\jenkins\workspace\Modeler-Build-6\modeler\Mendix.Modeler.Utility\BackgroundUtil.cs:line 28 at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e) at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument) Debugger was working in the past.

If you are running a version below Mendix 7 then please upgrade to at least Mendix 6.10.14 (https://docs.mendix.com/releasenotes/desktop-modeler/6.10):

  • We now use TLS 1.2 instead of the obsolete and insecure 1.0 version when remotely debugging an application in the cloud with the Desktop Modeler. (Ticket 64228)

Create a support ticket. I think the cause is the removal of support for everything below TLS1.2. You will get an error like this if one side is still on TLS 1 while it tries a service that only will support TLS1.2 and higher.
