They said it started over the weekend and multiple plugins included their own have been affected. They are working with their developers to fix the issue. Hopefully once the fix is applied, this plugin automatically works? Unless it also has to be updated. * [ajiaim](https://wordpress.org/support/users/ajiaim/) * (@ajiaim) * [7 years, 6 months ago](https://wordpress.org/support/topic/api-error-33/#post-10881829) * Mailchimp seems to have fixed this on my end… * [franzwolfgang](https://wordpress.org/support/users/franzwolfgang/) * (@franzwolfgang) * [7 years, 6 months ago](https://wordpress.org/support/topic/api-error-33/#post-10893372) * Same thing here: “Mailchimp says: API Request Error – on 1474 in /home/[website]/ wp-content/plugins/mailchimp-for-woocommerce/includes/api/class-mailchimp-api. php” * Any ideas how to fix this?

Since you’re currently receiving a 503 error code, that’s coming from Mailchimp’s API gateway service (Akamai). The quick and easy way to see if the problem was temporary, is to perform a fresh uninstall and install. If the problem persists, troubleshooting something like this is can be fairly technical and we suggest asking your host or a 3rd party developer for assistance if you’re not comfortable running the following commands: * The first step is to see if your server can communicate directly with the Mailchimp API using the CURL command below: * `curl -v -X GET https://{$DATA_CENTER}.api.mailchimp.com/3.0/ecommerce/stores? apikey={$API_KEY}` * Please replace the $DATA_CENTER and the $API_KEY with your credentials. You can locate the $DATA_CENTER number in the URL, for example `us19`. If you receive a valid response from the Mailchimp API, that helps us solve the first step of determining whether or not your server has been IP Blacklisted by the API gateway. * Once we’ve verified that you are able to make calls directly using CURL – we can then see if there might be another SSL handshake issue / OpenSSL / libCURL issue that might need to be addressed by your server admins. * Give that a try and let us know if it solved the issue. I look forward to hearing back from you. * [Anderson Carambola](https://wordpress.org/support/users/afbatera/) * (@afbatera) * [7 years, 6 months ago](https://wordpress.org/support/topic/api-error-33/#post-10918261) * Olá!
