Error 1020 don't have any firewall rule

If all the above you mentioned, that’s a bit weird :thinking:

However, are you sure there aren’t being any Firewall Rules enabled (green toggle button) at the Firewall Rules list? :thinking:

If you still get 1020, you should see it and be able to find it by the “Ray ID” in last 30mins or so, therefore determine what blocked your request from accessing your Website.

  • it might appear a minute or two later, not immediately …

May I ask have you tried using a different Web browser, or tried clearing your Web browser cache?
How about using a Private window (Incognito mode) or a VPN connection if possible?
Is it the same behaviour on your mobile phone (4G LTE, mobile data, cellular)?
