What Really Happens When OpenClaw Gateway Fails?

The most common trigger? A carrier-grade NAT timeout or a flaky MPLS link. OpenClaw maintains persistent QUIC connections to Cloudflare edges. If those connections drop and aren’t re-established within ~45 seconds, the tunnel supervisor marks them as "zombie" and refuses to re-negotiate.

The `SIGUSR2` trick is undocumented—OpenClaw treats it as a "reset elections" command. Works ~80 % of the time; otherwise a full restart is needed.

Look for `goroutine 1 [select]` stuck on a network call. This almost always points to egress connectivity problems.
