cURL error 7: Failed to connect to localhost

[Gudea]

I've been using Pabbly connect successfully for 3 days to create sales orders in Zoho inventory whenever a sales order is created in Woocommerce. But now suddenly it stopped. I checked the workflow, the first task is excuted sucsessfully and the Woocommerce order data are received but the task of Woocommerce meta data extractor has this error:
196 }197 198 // Create a connection exception if it was a specific error code.199 $error = isset($connectionErrors[$easy-&gt;errno])<b>200 ? new ConnectException($message, $easy-&gt;request, null, $ctx)</b>201 : new RequestException($message, $easy-&gt;request, $easy-&gt;response, null, $ctx);202 203 return \GuzzleHttp\Promise\rejection_for($error);204 }

I've received an email with this information:

Hey @Gudea

We checked your workflow and the task history shows that the workflow re-executed the errors and is working perfectly now. As there was an issue earlier which has been fixed.

Although, to avoid these errors, we would recommend you turning on the "simple response" button. Further, kindly map the values from "Res2" responses, instead of "Res1" and "Res3".

Let us know if it works for you.
