Hi,

Upgraded from 3.0 to 3.1 and now grafana can not connect, i have updated both webui and webapi.
The webapi is active but when you save and test in the grafana connector you get "HTTP Error Internal Server Error"

Can not find any logs that shows a description of the error found it

in the webui logs:

INFO: 2019-12-05 09:21:29 192.168.*.* admin 192.168.*.* 8083 GET /webapi/grafana/datacollection

Everything runs on the same server, netxmsd, webui and grafana

Edit:

Downgraded the webapi to "NetXMS web service API version 3.0.2296" then it worked again
