on the server that hosts the portal, enterprice and scheduler I don't see anything in the normal application or system event logs.  There is no solicp event log under applications and services.   We are using the standard version of windows 2012 r2 with the gui.  The scheduler has always worked, just not sure exactly when this started happening.  We can see from the audit log that some jobs run just not the jobs using the Check Web Site availability task...

We are using the normal install of windows with the gui, no issue there.

We do not see anything in the event logs either under app or system or under the application and services section.

Marco / Trevor - We have figured out what the issue is.  The job scheduler is working and running that error only happens for URL that are using HTTPS://.

The issue is that only TLS 1.2 is available on the receiving https:// domain.  For domains that still have TLS 1.0 enabled the scheduler call works.

My understanding is that you need v4.5.x framework for tls 1.2 support and these flags set as below. But I recall seeing the like for < 4.5.

4.5+

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls12 | SecurityProtocolType.Ssl3;

<4.5

ServicePointManager.SecurityProtocol = ServicePointManager.SecurityProtocol | (SecurityProtocolType)768 | (SecurityProtocolType)3072;

Hello,

Thank you for the further debugging and providing a URL for testing.

I can confirmed this has been fixed and will be included in the next release.

Kind Regards,

Trevor Robinson
