Hello, the last 6-7 days i have had troubleto use paypal express on my site.

I use Zen cart v1.5 with paypal express.
My host is host1.no and my url is www.elektroarena.net and www.makeupheaven.no
I have the same problem on both sites..

But sometimes the payment goes through. I get the error about 2 out of 10 times.

The error code is : (6) Couldn't resolve host 'api-3t.paypal.com'

I have talked to my host and they say that they can resolve api-3t.paypal.com at the same time as i get the error in my cart. So they say that there is no problem at the server.

What could be wrong?

The host i located in Norway, i use LIVE api server, and api signature.

I have a script called ipncheck.php where i get this error:
CURL ERROR: Attempted connection on: https://www.paypal.com/cgi-bin/webscr

(6) Couldn't resolve host 'www.paypal.com'

Trying direct HTTP on port 80 instead ...

CURL RESPONSE RECEIVED - Communications OKAY
IPN TESTING - Response Received via CURL -- COMMUNICATIONS OKAY



IPN TESTING - Confirmation/Validation response with fsockopen(): FSOCKOPEN() RESPONSE RECEIVED - Communications OKAY



Default method likely to be used for communications is: CURL, with the fallback method being FSOCKOPEN if possible.

Script finished.

And sometimes i get no error with the script.
