Timelion red error bar

[drudnicki (daniel)]

Hello,
I have problem with Timelion showing red bar at the top of the screen " Error Timelion: Error"
I can't find any more meaningful message. It does not react either, when I try to run a query.
It's Kibana 6.5.

However when I try to make timeseries-timelion visualization (using visualization tab) it seems to be working fine.

Please help, where to start solving this.

Hello,

Can you also look in your ES and Kibana logs to see if there's anything meaningful?

Hi,
I don't see anything relevant in ES logs.
I'm somehow not able to enable kibana logs. (I have set in kibana.yml elasticsearch.logQueries to true and logging.verbose to true and then restarted service).
EDIT: found logs in syslog :

Only status I can see in syslog for timelion is "304"..
