I am running Ignite Web Console and Web Agent in k8s v1.9, but connection fails when using security - works fine without security. I am able to access Ignite REST API by passing 'X-Signature' value in Header using Postman, but see no way to do this through the Web Console. Same with dBeaver.
Web Console do not support connection to secured cluster.
I created issue: IGNITE-8428 Web Console: Support connect to secured cluster.
You can track it.
