Sudden Paypal Issue

We are experiencing an issue with MembershipPro and Event Booking where people can book and pay via paypal but the status sticks on Pending even after the payment has been processed. I have looked in the IPN Log and there is a line that says:

Could not open SSL connection to www.paypal.com/cgi-bin/webscr

Could you please help?

Thanks

I think your hosting provider block the connection from your site to PayPal for some reasons. Please contact your hosting provider, ask them to see why this simple PHP command doesn't work:
If they don't block the connection, when run that PHP code, there should be Connection OK string being displayed

I have received this from the hostig provider:

Please have a try using the URL paypal.com instead of www.paypal.com in the script and have a check at your end. If the issue persist please provide a URL to check the connection to paypal so that we can check in detail.

Hi Simon

Please tell them that www.paypal.com works well for everyone (and worked for you before).

Ask them to create a PHP script contains the above code and run it themself so that they know the error

Thanks for your help, a quick update I received this:

Hello Simon,
This was due to a problem resolving www.paypal.com , which was the fault of an external DNS resolver in use on the server.
I have now demoted that resolver and confirmed that the next resolver is working properly.

OK Simon. That mean it works properly now. Please monitor the next registration and update us with the result

Regards,

Tuan

MembershipPro is now working properly now I'll keep an eye on Events.

Thanks for your help
