Paypal error: An error has occured and your payment has failed. Please try again

elliotpress, the log you just posted contains sensitive information. you need to change your paypal password and api credentials immediately.

I just removed it – just saw Ian’s post – but it’d already been up for 12 minutes – so likely already indexed widely.

So definitely get those credentials changed ASAP :)!

PSA for everyone: Whenever you post logs, please make sure you redact any sensitive information from them. If you’re not sure what may be sensitive or not, you can e-mail them to me privately at https://iandunn.name/contact/

elliotpress, the relevant info from the logs was this line:

http_request_failed Failed to connect to 173.0.84.69: Permission denied

That means your server couldn’t connect to PayPal’s API. I’d ask your hosting provider if they can figure out why, since that’s probably something on their end.

Hi tapandesai,
This may sound like a stupid question, did you double and triple check your Paypal API credentials. Login to your Paypal account, maybe if you copied and pasted your credentials you failed to copy everything.

Please check again your:
Paypal API Username
Paypal API Password
Paypal API Signature

Please don’t list any of your Paypal credentials here.

Hi WDjoe,

I already tripled checked everything but it was not working.

Hi Iann,

I configured everything correctly but it was not working. And then next morning, it was working perfectly. I don’t know how it was fixed automatically

Ian and WPyogi,

I am an idiot–thank you for alerting me to my misstep and removing the sensitive information. Changed my PayPal password and reset my API credentials; fortunately, no harm seems to have been done.

Ian, your suggestion to look into my hosting provider was spot on. Upon accessing my host’s control panel, I saw that several outgoing connections to PayPal had been blocked. After whitelisting the IP addresses, the plugin is working! THANK YOU FOR THE ASSISTANCE!!!

Any ideas on why this occurred? There are about 25 other outgoing connections that have also been blocked, and I have no idea what these are (or whether I should whitelist them or not).

Glad to hear it’s working again and that no damage was done ??

I can’t think of any reason why they’d block those connections, unless maybe they’ve had problems with hackers signing up for accounts and using them to attack PayPal or something. The only way to know for sure would be to contact them.
