Soon, Salesforce will be requiring all connections to be TLS v1.1 or higher. This poses a problem for anyone using SoapUI with Java version 1.7 as that version of Java does not have TLS 1.1 or higher enabled by default. If you attempt to connect to an instance that has the “Require TLS 1.1 or higher for HTTPS connections” enabled you will get an error like the following
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sf="urn:fault.enterprise.soap.sforce.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
