Unable to connect to https://tlstest.paypal.com

[rjvj]

Hello,

my merchant id in sandbox is <Removed>

I see the IPN message is sent to my IPN post back url. But, the PayPal response is empty when I receive it. It was working before (for a few years now) and not sure if something changed. However, IPN simulator is able to successfully post to my URL.

Our server supports TLS1.2 and when I open connection with PayPal, I get the following exception java.lang.ClassNotFoundException: com.ibm.jsse2.SSLSocketFactoryImpl; java.lang.ClassNotFoundException: com.ibm.jsse2.SSLSocketFactoryImpl

Here are the supported protocol versions - [TLSv1.3, TLSv1.2, TLSv1.1, TLSv1, SSLv3, SSLv2Hello]

When I run the TlsCheck.java, get inputstream from https://tlstest.paypal.com connection is empty (PayPal_Connection_OK message is not present).

Please help. Let me know if any other information is needed.

Thanks.

Hello,

The endpoint "tlstest.paypal.com" is no longer operational, which is why you're experiencing errors whilst attempting to connect to that URL. We used that during our migration to TLSv1.2 so people could use it to test, but once the migration was completed, the endpoint was retired.

nslookup tlstest.paypal.com
** server can't find tlstest.paypal.com: NXDOMAIN

For IPN, I'd recommend trying one of our IPN scripts which we provide here : https://github.com/paypal/ipn-code-samples

Thanks !
