Error 404: The login failed, what should I do?

Complete error description: Error 404: The login failed, what should I do?

Cause 

Sometimes, the connection between Nembol and WooCommerce keeps failing because there are block functions active on your Woo website, which rejects the connection with Nembol as a third-party app.

Solution

In this case, you should:

    • Turn OFF your Anti-spam filters.

    • Switch OFF the WooCommerce firewall, and retry with the whole login process explained above.

    • If even deactivating the firewall, you’re still not able to connect WooCommerce to Nembol, ask your domain provider to whitelist Nembol and retry.
