Auto IP Blacklisting

The IoT Hub has a attack detection in place: A high HTTP error rate within a short timespan will be rated as attack. To prevent overloads, attackers IP addresses are banned on the firewall for two days.

To prevent that your app gets blacklisted, please request (via support a permanent whitelisting for your servers IP or IP range.)
