Proposed title of this feature request

Using TLS or mTLS, LokiStack (configured on cluster A) should be able to accept logs coming from another (using RHOL configured on cluster B).

What is the nature and description of the request?

As collector (fluentd and vector) pods have capability to forward logs to Loki, so to have logs at centralized location (for eg: LokiStack), then there can be a way to forward logs to LokiStack which is hosted on another cluster using TLS authentication.

Why does the customer need this? (List the business requirements)

There are many customer who look forward to have logs at a centralized location. As elasticsearch is deprecated now and we have moved to Loki So, it can be used to store logs generated from multiple clusters.

List any affected packages or components.
