Hi Stefan, This could also happen because your PTR record of sending IP address resolves with 3 IPs e: IP 116.203.31.6 - PTR securetransport.cubewerk.de - IPs 178.254.23.77; 116.203.31.6; 188.68.39.254
I know that technically it is nothing bad but, I can imagine why some sensors could return errors, especially since the 3 IP addresses are from different ASNs: [image: image.png] I guess those 3 IPs are set as fallback in this situation?
