If you are getting this error, then the server does not have the definition for your ECU or the protocol is not supported.
If you want support to be added, please send a full file and a copy-paste of the status window to firstname.lastname@example.org.
A full file is:
Please don't send crypted files (e.g. CMDFlash VREAD, Autotuner VREAD), or files that only have maps inside (e.g. Flex VREAD, AutoTuner bench read, CMD bench read), as they are completely useless for any development.
If only the definition is missing, then most likely your definition can be added within a few minutes of you sending in the full file. For missing protocols it can take longer.
