I've been testing with a previous test PayPal account which was setup a few years ago for a website and everything works as expected in test mode. This uses HTML to populate the form and send to PayPal for payment. I change the settings from test to live on a completely new separate PayPal live account and attempt to make a live transaction. I reach the PayPal gateway, enter my LIVE email address which prompts me for a secondary authorisation (this is fine as I have set 2 factor authentication for my PayPal account)..... I authorise this and then receive a friendly error that the transaction could not go at further and to return back to the merchants website. Looking at the logs it shows a 4011 error but I'm not sure what settings I need to check out or any other changes to make? Could anyone narrow this down or give some ideas to try out?

Hello, As you never mentioned what type of transaction you've been conducting, I can't make a more specific response, but I would recommend using the "custom" variable to pass a value within the transaction request and which can be queried by conducting a GetTransactionDetails API call. https://developer.paypal.com/docs/classic/api/merchant/GetTransactionDetails_API_Operation_NVP/?mark=GetTransactionDetails

Hello, If your using a "saved" or "hosted" PayPal button you may have added the return URL within the options for the button. Check for "saved" / "hosted" buttons within the sandbox account where the payment is being sent and check the settings for these buttons to determine if a return URL was specified. https://www.sandbox.paypal.com/cgi-bin/customerprofileweb?cmd=_button-management

Im using a custom form to send to Paypal and take payment. At present I am using https://www.sandbox.paypal.com/cgi-bin/webscr for sandbox and https://www.paypal.com/cgi-bin/webscr for live payments. The PayPal site is reached, users can make a payment and are returned back to my site. If i visit https://tlstest.paypal.com/ in a browser from the server where my site is hosted i see PayPal_Connection_OK so this means to me the server is setup but i dont know if any further coding/configuration is required when the form leaves my site to go to paypal to take payments? Do i need to make any further changes to ensure all is setup for TLS 1.2?
