WebRTC: Streaming playback failed on the OriginCluster Push Edge node.

[MrYangPan]

WebRTC: Streaming playback failed on the Push Edge node within the OriginCluster.
Describe the bug
In k8s, source site cluster deployment is used, where the edge node WebRTC whip pushes the stream, and then the edge node WebRTC whop pulls the stream for playback. If the stream is pushed or pulled on the same edge node, it can be played normally. If it is not on the same edge node, it cannot be played and the stream cannot be returned to the source

Version
SRS v6.0.155

To Reproduce

vhost defaultVhost {
tcp_nodelay on;
min_latency on;

cluster {
        # Generated Coworkers DNS: srs-origin-1.socs.default.svc.cluster.local:1985 srs-origin-2.socs.default.svc.cluster.local:1985
