What's going wrong

Many site owners using this connector to link Contact Form 7 with MailerLite report that the API key check fails with a request failed or 401 error. Some say it began after an update, others after installing a second plugin such as a booking system or a WooCommerce mailer, and one reports a PHP library fatal. Owners who tested the key on the vendor's own playground found it valid, so the failure sits between the site and the service. Small businesses and freelancers setting up forms lose hours. A connection doctor that tests each layer and names the failing one would serve them well.
