Threat Emulation Appliance TE daemon did not respond or not running

[tytdoge]

Hi all,

i was setting up the TE appliance in the lab environment and everything are freshly installed.

However, after i enabled the Threat Emulation blade for the Appliance through Security Management Server.

i got error from the alert tab in smart console showing "Threat Emulation Error: Unknown" and when i login to the appliance and attempt to run "tecli" it showed:

>tecli

daemon did not respond or not running!

error: timeout reached

Also, i cant see the following error in $FWDIR/log/tecli.elg

[TE (TD::All)] te::AttributeReader::AttributeObjectHandlerString::FetchAttribute: Failed to read attribute data, can't find value for attribute: mail_archive_prohibited_file_types in attributes object, this might indicate that this attribute was not set yet

Can someone advise me what is the next step for trouble shooting? 

Thank you for your attention!
