title: Salesforce TLS 1.0 disable test link tls1test responding grant_type not support
body: <p>Since Salesforce TLS1.0 is getting disabled on July 22nd I was testing as suggested in the below url <a href="https://help.salesforce.com/articleView?id=Salesforce-disabling-TLS-1-0&amp;language=en_US&amp;type=1" rel="nofollow noreferrer">https://help.salesforce.com/articleView?id=Salesforce-disabling-TLS-1-0&amp;language=en_US&amp;type=1</a> .<br>
    We interact with salesforce from backend server via REST API Initiatilly we do a grant_type=password for getting the access token and instance_url.  Its pointed to <a href="https://login.salesforce.com/services/oauth2/token" rel="nofollow noreferrer">https://login.salesforce.com/services/oauth2/token</a> and it works now.  As mentioned in the help url tried to point it to  <a href="https://tls1test.salesforce.com/services/oauth2/token" rel="nofollow noreferrer">https://tls1test.salesforce.com/services/oauth2/token</a>   and it gives me an error {"error":"unsupported_grant_type","error_description":"grant type not supported"} .   Tried in the below format from linux command line it gives me the same response.</p>
  
  <pre><code> curl -v https://tls1test.salesforce.com/services/oauth2/token -d "grant_type=password&amp;client_id=&lt;&gt;&amp;client_secret=&lt;&gt;&amp;username=username%40domain.com&amp;password=&lt;&gt;" -H "Content-Type:application/x-www-form-urlencoded"
  </code></pre>
