NetXMS Support Forum

Hello,

I need you help working with NetXms WebAPI over https.

I deployed the NetXMS WebAPI using this guide https://wiki.netxms.org/wiki/Deploy_NetXMS_WebAPI_using_the_WebUI_Windows_installer_(Windows_only!).

The API is working fine with URL : http://netxms.mydomain:8080/webapi/ and also i can connect to it from grafana.

However when configuring grafana to use https and also set the following setting in grafana :cookie_secure = true, Grafana cannot collect data from  http://netxms.mydomain:8080/webapi/ .

Not sure if I'm asking the right questions here but long story short - how can i make https://netxms.mydomain:8080/webapi/ accessible?

Thank you,
Raoul

Hi!

If grafana is running in https mode, it will not accept datasources which are not from https url's.
The guide is a bit of a hack to get the API working with the same built in web server that comes with the windows WebUI installation. What I can suggest is to deploy a dedicated web server like Apache Tomcat and following this guide, configure it for SSL usage https://www.mulesoft.com/tcat/tomcat-ssl

Hi Eriks,

Thank you for your response.

I will follow the guide you provided.

Hi again,

So, I have deployed NetXMS WebAPI with Tomcat 9 instead of Jetty and it doesn't work even with http.
I have attached the Catalina log and also Wireshark traces.
Tried this with Tomcat 7 and 9.

What am I doing wrong?
