PayPal EC API error

[tinypack]

Yesterday I received this error as someone was checking out using PayPal Express checkout:

- (6) Couldn't resolve host 'api-3t.paypal.com'

I received the order and payment fine. But I have noticed that the paypal pages are running very slow when I do a test order.

I contacted Paypal and this is the response I received:

You're using a wrong endpint. Take a look at the list below and make sure you are using the correct one.

Endpoints:
Live API Certificate Name-Value Pair https://api.paypal.com/nvp
Live API Signature Name-Value Pair https://api-3t.paypal.com/nvp
Live API Certificate SOAP https://api.paypal.com/2.0/
Live API Signature SOAP https://api-3t.paypal.com/2.0/
Sandbox API Certificate Name-Value Pair https://api.sandbox.paypal.com/nvp
Sandbox API Signature Name-Value Pair https://api.sandbox.paypal.com/nvp
Sandbox API Certificate SOAP https://api.sandbox.paypal.com/2.0/
Sandbox API Signature SOAP https://api.sandbox.paypal.com/2.0/


I am not sure what to do with this information and I am looking for some guidance.

I have 1.3.8 (some of 1.3.8a)

Zen Cart is correctly using the required endpoint:

Live API Signature Name-Value Pair https://api-3t.paypal.com/nvp

PayPal has been having problems with some of their "3t" servers since their recent maintenance updates in the last couple weeks. You might get more attention if you keep complaining to them when the problem occurs.

Additionally, if the "cannot resolve host" message is constant, you may have a problem on your hosting company's webserver with respect to DNS lookups, and should be reporting the matter to them.

Thanks, I'll keep an eye out for more errors and talk with my host if necessary.

I've having this same problem quite frequently. Sometimes 20 times in a day. It's been going on for the past week and is very frustrating.

I reported it to PayPal and they basically said they couldn't figure it out because it was intermitant. They requested I ping their server right when it happens. As you can imagine, that's pretty much impossible.

I am still getting this error intermittently. In addition I received this error this morning:

10002 Authentication/Authorization Failed - Internal Error

I have sent a follow up email to PayPal support. I suspect a misconfiguration with my API settings since I recently moved my store to a new domain. Still doesn't explain why these issues showed up over a month after the fact. I am concerned because these issues are hurting conversions.

I will post any responses I receive. Also sending a support ticket to my host.

Still no answer from PayPal about the API error. They did respond to my inquiry about this error:

10002 Authentication/Authorization Failed - Internal Error

This error occurs because you need to set your permissions in your PayPal account. In order for a third party to make API calls on your behalf, you have to explicitly grant them permission to do so.

I could not find any instructions from the zen-cart instructions for this. So I think this is just a lazy answer?

I sent a follow-up about the API error - which they have so far ignored.
