UNSUPPORTED_CLIENT TLS 1.0 has been disabled

We are attempting to setup the application using the acceptance login details for SalesForce, there is an issue in regards to TLS 1.0
We are using partner WSDL   to call the soap api, but we faced a issue while calling the login function.
Below is the error:
"UNSUPPORTED_CLIENT TLS 1.0 has been disabled in the organization. Please use TLS 1.1 or higher"

Hi Bhushan, currently allows the disabling of TLSv1, a security protocol used by web services to talk to each other. If this version of TLS is disabled in your Salesforce service, Soapbox Engage will not be able to function properly in some cases, since some of the Soapbox Engage servers still require the use of TLSv1.

In order to deactivate this in your organization follow these steps.

1) Search for "Critical Updates" in your quick find box.
2) It will show the list of updates. You have to deactivate "Require TLS 1.1 or higher for HTTPS connections" in that list.

Now you will not see that error.

Mark it as solved if it works for you.

That worked for me but for some reason it keeps auto-activating.

When I went to de-activate it says:
NOTE: This update will be permanently activated on the auto-activation date. You can activate and deactivate this update for testing purposes until that time. 

And when I go to activate it:
Starting in June 2016, Salesforce will begin disabling the TLS 1.0 encryption protocol using a phased approach.

So does that mean this solution no longer works?

Please check below post for this problem ans solution. I hope that will help you

Hello, when I execute SOAP, I got the following error message. 

<Soapenv: Envelope xmlns: soapenv = "" xmlns: sf = "urn:" xmlns: xsi = "http: // ">
   <Soapenv: Body>
      <Soapenv: Fault>
         <Faultcode> sf: UNSUPPORTED_CLIENT </ faultcode>
         <Faultstring> UNSUPPORTED_CLIENT: TLS 1.0 has been disabled for this organization. To connect to Salesforce using HTTPS, please use TLS 1.1 or later. </ Faultstring>
            <Sf: UnexpectedErrorFault xsi: type = "sf: UnexpectedErrorFault">
               <Sf: exceptionCode> UNSUPPORTED_CLIENT </ sf: exceptionCode>
               <Sf: exceptionMessage> In this organization TLS 1.0 has been disabled. To connect to Salesforce using HTTPS, please use TLS 1.1 or later. </ Sf: exceptionMessage>
               <Sf: upgradeURL> </ sf: upgradeURL>

            </ Sf: UnexpectedErrorFault>
         </ Detail>
      </ Soapenv: Fault>
   </ Soapenv: Body>
</ Soapenv: Envelope>

So, although I want to deactivate  "Require TLS 1.1 or higher for HTTPS connections" from critial updates list, there is no such updates in my critial updates list. What should I do? Could you tell me answer, please? :(

If you face any issues in establishing the TLS connectivity from Soap UI, follow these steps to fix the issue:
Step – 1:  Navigate to C:\Program Files\SmartBear\SoapUI-5.2.1\bin folder.
Step – 2 : Edit SoapUI-5.2.1.vmoptions file with any text editor.
Step – 3 : Add following entry and save the file. It will only enable TLS 1.1 protocol.
If you have a requirement to enable other TLS version too, then use comma separated values as shown below.
Step – 4 : Close and Re-launch the Soap UI.
