Hello.
Since last daily update, every host on my LibreNMS has this error (if I click Capture/Discovery/Run), if I just go to Devices/Manage Groups/Rediscover all devices of device group, it seems there are no errors:
Error discovering discovery-protocols module. Check log file for more details., which results in all LLDP hosts disappearing.
My daily.sh is the following:
