Solution: 

1. Verify you are in https://app.erply.com/live

2. Verify that the IP address in your hosts file is the same as the IP address of the terminal. To see the IP address of a terminal you can follow these steps.
3. Verify that the Certificate of authentication is active, you can do this by going to the terminal address in your browser

• Terminal address: [POIID] = [Terminal model]-[Serial number]

For example P400Plus-123456789.test.terminal.Adyen.com

If the certificate of authority is correct you should see the message “Internal Server Error”

4. Verify that Adyen.com domain is whitelisted from your firewall if you have an active firewall.

If after this checkup you are still getting the A4 error, restart the EPSI.
