Title: Authentication problem with World4you Last modified: August 21, 2016 --- # Authentication problem with World4you * [stefanpapp6662013](https://wordpress.org/support/users/stefanpapp6662013/) * (@stefanpapp6662013) * [12 years, 7 months ago](https://wordpress.org/support/topic/authentication-problem-with-world4you/) * Hi, * As a follow up of [http://wordpress.org/support/topic/cant-find-the-mailchimp-list?replies=6#post-4883965](http://wordpress.org/support/topic/cant-find-the-mailchimp-list?replies=6#post-4883965) I create a new topic. * At least two users have problems authenicate the API Key with MailChimp from a World4you provider. The problem is described in the old topic. * I have a similar wordpress-site with a different provider and with this provider I can connect successfully. On this similar wordpress-site I have an identical setup such as the problematic ones (same plugins). Only difference is the theme Avada 3.1.1. in problematic site and Avada 3.1.2 in working site (which I doubt is the problem) * Stefan * [http://wordpress.org/plugins/mailchimp/](http://wordpress.org/plugins/mailchimp/) Viewing 12 replies - 1 through 12 (of 12 total) * [mc_gabe](https://wordpress.org/support/users/mc_gabe/) * (@mc_gabe) * [12 years, 7 months ago](https://wordpress.org/support/topic/authentication-problem-with-world4you/#post-4322440) * Hey Stefan, * Thanks for creating this new topic. We are trying to track this issue at the moment to see any commonalities we might be able to between situations which appear to be similar. In order to do this, we want to collect as much information as possible. Can you give this consolidated information here in this thread? * Things like: - Version of plugin - Version of WordPress - Host - Which particular step in using MailChimp appears to be failing. What piece of data are you having issues getting? - What message (if any) are you getting? * It sounds as if your host (which was mentioned as being the same as a host in the previous thread) may be blocking some ingoing or outgoing traffic to MailChimp’s servers, so checking with your host about potential ports or traffic being blocked, thereby disrupting standard functionality. * We appreciate any details you can provide. -Gabe * Thread Starter [stefanpapp6662013](https://wordpress.org/support/users/stefanpapp6662013/) * (@stefanpapp6662013) * [12 years, 7 months ago](https://wordpress.org/support/topic/authentication-problem-with-world4you/#post-4322446) * Plugin-Version: 1.3 Wordpress: 3.7.1 Host: World4you IP-Adress: 81.19.145.58 * Steps to reproduce 1.

Are there any news on this? * Thanks in advance! * Only difference, I’m using Plugin Version 1.4.1 * By the way, I’ve tried another plugin (MailChimp for WP Lite), connecting via the api key didn’t work neither. * KR Philipp * Plugin-Version: 1.4.1 Wordpress: 3.7.1 Host: World4you IP-Adress: 81.19.145.157 * Steps to reproduce 1.

(in my case, it only took 1hr 🙂 * custom web service calls and 3rd party plugins like MailChimp for WP Lite worked, but MailChimp List Subscribe Form still could not connect! * [mc_tak](https://wordpress.org/support/users/mc_tak/) * (@mc_tak) * [12 years, 7 months ago](https://wordpress.org/support/topic/authentication-problem-with-world4you/#post-4322509) * Hey philipneu, * Do you happen to know what they’re specifically blocking? And you mentioned that the plugin is still not working for you. Can you clarify whether you’re seeing the same “Uh-oh, Sie haben noch keine Listen..” issue or something different? * Thread Starter [stefanpapp6662013](https://wordpress.org/support/users/stefanpapp6662013/) * (@stefanpapp6662013) * [12 years, 7 months ago](https://wordpress.org/support/topic/authentication-problem-with-world4you/#post-4322515) * Hi, * mc_tak: Can you send me the exact URL where the plugin connects to? World4you requests it to make sure they can open an outgoing connection. * thank you! * Background: * I talked with World4You. Here is their reply (in German). I guess google translate will translate it somewhat correctly. * Externe Verbindungen werden standardmäßig blockiert. Wenn Sie uns die URL mitteilen wohin sich das Script verbinden will, können wir eine Freischaltung dieser dann prüfen. Eine generelle Freigabe ist nicht möglich. * Teilen Sie uns bitte das externe Ziel (ganz genaue URL) mit auf das sich das Script verbinden muss. Wir können eine Freischaltung dieses Ziels dann prüfen. * [mc_tak](https://wordpress.org/support/users/mc_tak/) * (@mc_tak) * [12 years, 7 months ago](https://wordpress.org/support/topic/authentication-problem-with-world4you/#post-4322516) * Hey Stefan, * For versions of the plugin 1.3+, you’ll want to have the host allow connections to “[https://sopresto.socialize-this.com/mailchimp/”](https://sopresto.socialize-this.com/mailchimp/”);. * For versions of the plugin prior to 1.3, you’ll want to have them allow connections to “[http:// is the datacenter your account is on. Ex. “[http://us2.api.mailchimp.com/”](http://us2.api.mailchimp.com/”);. If you’re testing other third-party MailChimp plugins that use API keys and are seeing issues, you’ll want to follow these directions too. * Let us know if there’s any additional questions or you’re still seeing any issues. * -tk * Thread Starter [stefanpapp6662013](https://wordpress.org/support/users/stefanpapp6662013/) * (@stefanpapp6662013) * [12 years, 7 months ago](https://wordpress.org/support/topic/authentication-problem-with-world4you/#post-4322520) * I talked with World4you, they answered that they can’t enable the URL in their system. The system engineer says the most probably reason is that the domain redirects to [http://wordpress.org/plugins/social/](http://wordpress.org/plugins/social/) weiterleitet. * Is there any other way? * [mc_tak](https://wordpress.org/support/users/mc_tak/) * (@mc_tak) * [12 years, 7 months ago](https://wordpress.org/support/topic/authentication-problem-with-world4you/#post-4322521) * Hey Stefan, * If that outgoing connection to that URL is being blocked, I’m afraid that the plugin won’t be able to work from version 1.3 onward. If they’re able to allow outgoing connections through the other URL that I posted (.api. mailchimp.com, [http://status.mailchimp.com/which_datacenter_am_i_using](http://status.mailchimp.com/which_datacenter_am_i_using)), you should be able to use version 1.2.14: [http://wordpress.org/plugins/mailchimp/developers/](http://wordpress.org/plugins/mailchimp/developers/) * Otherwise, you may consider trying the MailChimp embed code, which is outlined here: [http://kb.mailchimp.com/article/how-can-i-add-my-signup-form-on-my-website/](http://kb.mailchimp.com/article/how-can-i-add-my-signup-form-on-my-website/) Viewing 12 replies - 1 through 12 (of 12 total) The topic ‘Authentication problem with World4you’ is closed to new replies. * ![](https://ps.w.org/mailchimp/assets/icon.svg?rev=3156997) * [Mailchimp List Subscribe Form](https://wordpress.org/plugins/mailchimp/) * [Frequently Asked Questions](https://wordpress.org/plugins/mailchimp/#faq) * [Support Threads](https://wordpress.org/support/plugin/mailchimp/) * [Active Topics](https://wordpress.org/support/plugin/mailchimp/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/mailchimp/unresolved/) * [Reviews](https://wordpress.org/support/plugin/mailchimp/reviews/) * 12 replies * 5 participants * Last reply from: [mc_tak](https://wordpress.org/support/users/mc_tak/) * Last activity: [12 years, 7 months ago](https://wordpress.org/support/topic/authentication-problem-with-world4you/#post-4322521) * Status: not resolved
