Hi there,

Unfortunately I'm not exactly sure about your issue here. The error message "HTTP/1.1 400 Bad Request" is not returned by a SNMP sensor, it's returned by a HTTP call. Please let us know where this message is displayed.

Kind regards,
Birk Guttmann, Tech Support Team

Thank you.

Last time, i found this issue. Maybe the name of sensor was not UTF-8 format following Telegram definition.
