Error while using FedEx as shipping method

[deepali01]

Hi,

I am getting below error while using FedEx as a shipping method. I have added all the information needed in Magento 2.3.3 for FedEx.

Please let me know what could be the possible reason for the below error.

[2019-12-13 16:49:40] main.CRITICAL: Error Fetching http headers {"exception":"[object] (SoapFault(code: 0): Error Fetching http headers at /var/www/html/vendor/magento/module-fedex/Model/Carrier.php:508)"} []

@deepali01 have you already checked closer in your var/log/exception.log and var/log/system.log? Also, is this an unaltered version of Magento or do you have extensions and modifications installed? Have you already check with your hosting provider to see if they have any insight? What version of PHP are you using?

Assuming that your credentials are valid, open your php.ini file and change the value of the following variable:

default_socket_timeout = 120

Restart your webserver and try again.

Hope that helps!

We already did this setting still no effect. Although, the FedEx work fine at our local development environment but not working on our staging environment.

The log attached is from var/log/exception.log. Yes, there are some paid extensions we have used in our application. PHP version we are using is 7.1.33
