[OPEN] Increase supported TLS version for AWS sensors

User Story

As a PRTG User, I want to use TLS 1.2 and, when supported by AWS, TLS 1.3.

Details of User Story

I have TLS 1.0 and lower disabled in my environment (PRTG Network Monitor x64 on Windows Server 2012 R2). This results in the following errors from, for example, the Amazon Cloudwatch EC2 sensor in the gui:

Could not create the sensor Amazon CloudWatch EC2 BETA on device MyDevice (x.x.x.x). A WebException with status ReceiveFailure was thrown.

Manually running the sensor results in the following:

AWSv2.exe -ak="ACCESSKEY" -sk="SECRETKEY" -service="EC2"
?<?xml version="1.0" encoding="utf-8"?>
  <text>A WebException with status ReceiveFailure was thrown.</text> 

In .net 4.5, the default is only Ssl3|Tls. this can be expanded with System.Security.Principal: ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls | SecurityProtocolType.Ssl3;

Acceptance criteria

  • Have TLS 1.2 working
  • Have TLS 1.3 working, once released

Hi there,

What .Net Version is currently installed on the Core Server? We would recommend .Net 4.7 to make these connections possible.

Best regards.

Core server has version 4.7.02053 installed. I was told by support that PRTG is "using an SDK from Amazon that only supports TLS 1.0 at the moment." so this is a feature request.

I took the freedom and edited the first post to be properly formatted.
