If your server shows "Invalid Hostname" when querying on the serverlist, this usually means you are accessing a domain (or IP) pointed to our network, but not actually registered within our database.

Causes

• You have a SRV record pointed directly to your server.ipv4.tcpshield.com CNAME

• You are connecting directly to your CNAME (similar to SRV)

• You have not registered your domain with TCPShield

• You have misspelled your domain name when entering it in the dashboard

Fixes

• If you have an SRV record, ensure it is going to a target that is registered on TCPShield (for example a subdomain that is already pointing to the protected CNAME)

• Ensure the domain you're attempting to reach is registered within your dashboard, with a reachable backend IP

• If it is registered, ensure it is spelled properly
