TLS setting

Hi I am looking for advice. I was loading data to salesforce using a data loader tool that we have (3rd party custom built tool). I had activated the critical update for the Require TLS 1.1 or higher for HTTPS connections and this has caused my loader tool to fail. It is accessing salesforce by webservices using https://www.salesforce.com/services/Soap/u/25.0 . When I deactivate the critical update the tool Works. In the application I have only four possible inputs: URL, file to be uploaded, username and password+token. Is there any way to bypass or correct the new connection method? Does anybody know what webservices address I should put now to meet the TLS requirements. (I hope I am explaining my issue well).

Thanks,
Aidan

Hi Aidan,

You will need to work with your vendor who developed this tool to ensure this tool supports TLS 1.1 and above. Please refer the below link
