Hello, I had a server error (500). Then i checked Error log form Log files. And i figured out this error like this,
requests.exceptions.ProxyError: HTTPSConnectionPool(host='sandbox.sslcommerz.com', port=443): Max retries exceeded with url: /gwprocess/v4/api.php (Caused by ProxyError('Cannot connect to proxy.', OSError('Tunnel connection failed: 403 Forbidden'))) 2020-09-14 18:25:12,937: Internal Server Error: /payment/pay/
My url path is okay. And i think this error shows because of Whitelist. I checked the Whitelist , and there is no api.ssl-commerz or ssl-commerz.com or sandbox.sslcommerz.com in that whitelist. I think ssl-commerz api is not added in white list and perhaps that's why i m getting an error. Could you please add it?
