Hi @todor,
Could you share more info on how you run and configured Kibana?
Could you also [share failed network requests as HAR](https://developers.google.com/web/tools/chrome-devtools/network/reference#save-as-har)? (please make sure there are no sensitive data first).

Hi @dosant,
My Kaspersky protection was creating the problem.
When I turn it off, it worked.
Thanks for the reply.
