Nginx Integration Error: The agent was not able to collect your application logs
I’ve set /etc/nginx/json_access.log with 777 ( Test Server ) and see the json logs.

Grafana Agent Log: https://pastecode.io/s/o1sa9u18
Server Hostname: vultr
Website Name: xyz.medd.com.au

Yaml: https://pastecode.io/s/d1djb566

I am totally confused as I am not able to understand grafana-agent logs

Thank you
