Sandbox - Connection Private Issue

[Alex_cp]

 I am using Payment Data Transfer and I am attempting to use Paypal Sandbox for testing. It stopped working correctly but I haven't made any changes so it looks like the issue is on Paypal's end.

When I click on a subscription button it takes me to Sandbox Paypal where it offers me to create a paypal account or login with Paypal.

Choosing the login option, a warning screen is showned and indicates the following information:
"Your connection is not private Attackers might be trying to steal your information from www.sandbox3.paypal.com (for example, passwords, messages, or credit cards). NET::ERR_CERT_COMMON_NAME_INVALID This server could not prove that it is www.sandbox3.paypal.com; its security certificate is from www.sandbox.paypal.com. This may be caused by a miconfiguration or an attacker intercepting your connection. Proceed to www.sandbo3.paypal.com (unsafe)" .

If I tell chrome to proceed anyway it allows me to view the generic login in the following url: https://www.sandbox3.paypal.com/signin/?returnUri=https%3a%2f%2fwww%2esandbox3%2epaypal%2ecom%2fus%2... (note that the htpps:// is red and scratched).

After logging in, it takes me to "my account" and doesn't ask me to confirm the payment.

NOTE: Before the request error, this issue was already happening.

Here is a stackoverflow question showing the problem - https://stackoverflow.com/questions/44640024/paypal-sandbox-ssl-issue-redirect-issue/44652397

Hi,

I have been facing this problem since last one week, I have called the customer support many times and they sent me a link which doesn't work.There is no way to talk to the technical team as well.

 I am trying to do a test transaction in a sandbox mode. When i try to make payments it shows a window, 'YOUR CONNECTION IS NOT PRIVATE'. I have troubleshoot all my browser problem, there is no issue with my browser. I have even checked it in several other computers and mobiles, it's showing the same problem.

Please help!

Thanks,

Hi @zenney,

Add an exception for the certificate warning and it won't appear again. We're aware of the issue and are working to resolve it.

I am having a similar issue: I developed a website using WordPress, on which I tried two different plugins for PayPal donations. Since I have to develop custom code to handle post-donation operations, I need to be able to use the sandbox, which in both cases is referenced through the endpoint https://www.sandbox.paypal.com/cgi-bin/webscr. After specifying the donation amount and logging in, the PayPal sandbox redirects me to sandbox3.paypal.com, which at the present time is not available at all; this means that I'm getting a page unavailable error and I cannot complete the test payment. Unless I'm missing something, it looks like there are still some references on your end to update; are you able to confirm this?

Hello,

I've tested some donation button code within the sandbox environment today and I'm able to complete the donation successfully, there was no re-direction to "sandbox3.paypal.com".

Please share the code for your subscription button.

Thanks for your reply, I will post the HTML form being rendered as the PHP code is not very indicative of the final output.

</form>

As far as I can tell, there were no direct references to sandbox3 throughout the code, and the https://www.sandbox.paypal.com/cgi-bin/webscr handle seems to be the only entry point; I'm suspecting that either it's an outdated URL, or that some of the variables may be leading to a code block with obsolete references. Hope this helps, thank you and let me know!

I am still having this issue, how do I resolve this? This site can’t be reached www.sandbox3.paypal.com’s server IP address could not be found. Try running Windows Network Diagnostics. DNS_PROBE_FINISHED_NXDOMAIN
