Failed to communicate with QUIC.cloud/ The callback validation Failed
-
Hi! I can’t get Domain Keys anymore. Several sites which I have been trying last weeks are displaying these message when I try:
Failed to communicate with QUIC.cloud server: The callback validation to your domain failed. Please make sure there is no firewall blocking our servers. Response code: 403
Could you help me, please?
