Thanks a lot for your reply.
However - I tried it with all combinations of IPIN URL
All have not given me any go..........
I request someone from Bitnami team to try this configuration with valid paypal account and not sandbox account.
There is some catch somewhere in IPIN path or something.
To give you more details.............
I have installed this stack on EC2 server as single installation only as per your standard Bitnami guideline document.
Also later on converted this installation with SSL certificate successfully - as per Bitnami guideline documents. SSL certificate configuration is based on documentation - Let's Encrypt SSL Certificate For A Bitnami Application
All this got successful and my site is well running on https.............
I had configured PayPal account a fresh - Business account with all varifications and confirmations done and Pay pal account is receiving payments if i create separate Pay button on my another site. So there is no issue at all in my PayPal site as well.
I successfully configured Paypal payment method for my course and its well appearing also on course detail page.
I request you to try One of My course TYBcom IT which I purposefully kept at just US 0.10.
You cantry to Pay thi course using PayPal button and then choosing credit or debit card option.
After putting correct details of credit or debit card..........
After submitting.......it throws error........
The payment can not be processed at this time. Request to please go back to merchant site and try another method.
This is real frustration and not getting to any solution after struggle for more than week.
My course currancy is in USD as it can not be set in INR. My PayPal account is in India and set to receive both currencies - USD and INR.
PayPal is now allowed for Indian currencies and all legal documentations are done with Paypal account and good to go.
I request Bitnai team to look deep in issue. and guide.
I still presume there is something wrong with IPN Path that is set in IPN notification. I presume IPN notification is not reaching to intended ipn.php file and hence no response is coming up.
