 * Hello,
 * Is this a new installation? If so, please verify that the API URL and Key are
   correct and try again.
 * If you know the API URL and Key are correct, check with your web host to ensure
   that they are not blocking communications from the ActiveCampaign server.
 * It could be an issue with the ActiveCampaign’s servers.

 * Hi [@equalserving](https://wordpress.org/support/users/equalserving/) ,
 * Thank you for your prompt response. Yes, this is a new installation.
 * I’ve double-checked the API key and even re-entered it yesterday, but unfortunately,
   the issue persists. I will reach out to my hosting provider to confirm whether
   communications from the ActiveCampaign server are being blocked.
 * ActiveCampaign has already verified that their servers are functioning properly.
   I’ll update you as soon as I hear back from my hosting provider.
 * Best regards,
