Answer 1

Hello,

for me the solution from this thread helped: https://www.knowage-suite.com/qa/752/problems-accessing-to-cockpits
As you were asking there which files to change here some more details.

Open the server.xml file in the conf directory.

the service_url can stay at localhost

and the host_url needs to be adjusted to the correct ip.

Below the lines in detail:

<Environment name="service_url" type="java.lang.String" value="http://localhost:8080/knowage"/>
<Environment name="host_url" type="java.lang.String" value="http://your_network_ip_here:8080"/>

Hope it helps.
