Please let me know if you get it working. I am still struggling.

It says you have no pollers enabled.

Check the cron file is installed and working if you are using the python wrapper
or check the dispatcher service is running if you are using that.

5

Can you give us some pointers on where to start to look? Not too familiar with the internals

The CLI validate you posted is not running as the librenms user - try that again to see if any different.

Follow through the install doco to check your cron entries are as required: Installing LibreNMS - LibreNMS Docs

The dispatcher service if you’re using that (you’d probably know if you were) is here: Dispatcher Service (RC) - LibreNMS Docs

I do not make use of any pollers, but did do some testing with it, so had ones that was no longer being used. When I removed my unused pollers it solved the problem for me.

So my suggestion would be is to delete your pollers that is not being used.
