Missing logs in Loki

issue: logs missing in loki

description: I am in the process of migrating from ELK to Loki. I have set up Loki in distributed mode and container S3 as log storage. All services are working fine but when I compare logs between Loki and already running ELK, i see a lot of logs missing in Loki. This is a show stopper from going further with Loki set up.

Thanks
