Error suggest that you are using TLS1.0 which is nto supported by client(salesforce in your case). Salesforce is disabling the support of 1.0 due to securtiy issue. You may ask your IT team to upgrade it o 1.1 or 1.2. Please check following KB for more information (https://help.salesforce.com/apex/HTViewSolution?id=000221207
