ServiceNow exports failing due to incompatible TLS versions
When running a ServiceNow export from FNMS to ServiceNow, you may encounter one or more errors related to connection or secure channel errors such as:
ServiceNowConnectionTest.SendTestConnection: Error Checking Connetion to endpoint: api/x_fls_flexera_fnms/integration/fnmstosn 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 FNMP.ServiceNow.HTTP.ServiceNowRequest.WriteData(HttpWebRequest request, String content) at FNMP.ServiceNow.HTTP.ServiceNowRequest.Post(String content) at FNMP.ServiceNow.HTTP.ServiceNowConnectionTest.SendTestConnection() [2019-09-08 03:01:50] - [DEBUG]: Exiting ServiceNowConnectionTest.SendTestConnection
This has been identified as related to the changes ServiceNow made to disable both both TLS 1.0 and TLS 1.1 
This process appears to have been in an instance-by-instance basis so not all customers are experiencing this issue.
