Error messages during the activation or before importing a sample slider

1
28Connection timed out after X milliseconds

This error message can happen if your server is not able to connect to our website. Usually this is caused by a firewall or the server is not connected to the Internet. You should contact your server host and ask them to help you resolve this problem.

As a test they could connect to the SSH of the server and run this command:

ping api.nextendweb.com
	

It should return data.

2
35OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to api.nextendweb.com

This error message can happen if your server is not able to connect to our website. Usually this is caused by a firewall or the server is not connected to the Internet. You should contact your server host and ask them to help you resolve this problem. As a test they could connect to the SSH of the server and run this command:

ping api.nextendweb.com
	

It should return data.

"7Failed to connect to" errors

Server can't reach IPV6 addresses

Create a PHP file, and put this code inside it:

<?php
// create curl resource 
$ch = curl_init(); 

// set url 
curl_setopt($ch, CURLOPT_URL, "api.nextendweb.com"); 

//return the transfer as a string 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

// $output contains the output string 
$output = curl_exec($ch); 
var_dump($output);

// close curl resource to free up system resources 
curl_close($ch);
?>
	

Upload it to your website via FTP, and take a look at it in your browser: http://example.com/test.php

If you will see it return " false", then the problem will be, that for some reason your server doesn't let your website reach IPV6 addresses. You should contact your server host, and ask them why this PHP file's code cannot reach our IPV6 website ( https://nextendweb.com ), because it should be able to.

If it really can't reach it for some reason, then they should turn off IPV6 on their server all together, and in this way curl won't try IPV6 connection, but IPV4 instead, which would probably work.

But if you see something else, then contact us, because in rare cases we have to add IP addresses to our whitelist to let them connect to our server.

6Could not resolve host api.nextendweb.com

This problem happens, when the server's firewall blocks all incoming data from external websites or if the IPV6 is mis-configured on the server. Get in touch with your host and ask them to fix the problem.
