Invalid API key. Please check your API key or reconnect the site and try again

Hello,

I’m sorry to hear that you’re facing issues with the API key. To resolve the “Invalid API key” error, please follow these steps:

1. Change Your API Key: If you haven’t already, try changing your API key by following the instructions provided in our knowledge base article here. Once done, remember to click on the Save Changes button.

2. Clear Website Cache: After changing the API key, clear your website cache.

3. Wait for a Few Hours: It’s recommended to wait for a few hours before submitting another URL after changing the API key.

If the issue persists after following these steps, it might be due to another site on your server using up the quota assigned to your shared IP address. In this case, you may need to wait it out or contact your hosting provider for further assistance.

I hope these steps help resolve the issue with the API key. If you have any further questions or need assistance, feel free to ask. Thank you for reaching out to us!
