Log4j > Loki API

Hi everyone, is anyone out there using the custom appender for log4j to send logs to Loki - https://github.com/tkowalcz/tjahzi/tree/master/log4j2-appender
Its mentioned in the Loki docs Send log data to Loki | Grafana Loki documentation

Using this XML works from a local device to send to Loki but when deployed at a cloud location in Prod we don’t get anything in Loki. Have already doublechecked the VPN tunnel and firewall - nothing blocking traffic there.

Any thoughts?
