WooCommerce: Solve common problems

Restore the connection

To verify that the API keys are correct, follow the steps given in Connect to Mollie.

If you have the Admin role, you can also perform the following tasks:

  • Ensure that external connections to https://api.mollie.com are not blocked by a site- or server firewall.

  • Ensure that SSL v3↗ is disabled on your server.

  • Ensure your server is up to date and that the latest security patches have been installed.

  • If applicable, ask the organisation hosting your server to send a cURL request to port 443 on api.mollie.com via PHP.
