Hi,

You have two options:

  1. Configure mysql socket like in here Poller Not Running from Cron

  2. Change db_host in config.php and DB_HOST in .env to point 127.0.0.1 instead localhost. You will also need to change de librenms sql user from ‘librenms’@‘localhost’ to ‘librenms’@‘127.0.0.1’

Thank you TheGreeatDoc! It helped. Everything is working now!
