PayPal Standard return URL error

Hi all,

I have read all the setup and every forum post I can find on this topic.

I have a paypal sandbox account setup, using the paypal merchant account for testing. I have my test site on an azure web app service for testing with a sql server database.

No matter what settings I use for the setup on the paypal plugin I am always faced with the following page

"We're sorry, an internal error occurred.

Our supporting staff has been notified of this error and will address the issue shortly.

We apologize for the inconvenience. " etc....

with the following URL http://#######.net/errorpage.htm?aspxerrorpath=/Plugins/PaymentPayPalStandard/PDTHandler

I am using nopcommerce 3.7.

I have followed all of the setup and configs and my return URL in paypal sandbox is configured as follows,

http://######.azurewebsites.net/Plugins/PaymentPayPalStandard/PDTHandler

Thanks for any help.

I am using on azure without any problems, just not using the sandbox. It works fine.

can you check from logs what kind of error are you getting?

Thanks Dia,

here is the log from the azure server

Just looking below and spotted this in the log

Could not create SSL/TLS secure channel.

I did turn the Block Non-encrypted Website Payment:option to off in the website payment preference section in sandbox.
