Lovable engineers debugged two layered networking failures in their Google Kubernetes Engine cluster.
First, a concurrent map-access panic in Google's anetd WireGuard integration code caused pod crashes.
After disabling transparent node-to-node encryption, a second issue emerged: an MTU mismatch between nodes that had and had not restarted, causing connection failures to Valkey.
The fix required rolling all nodes to ensure consistent MTU configuration.
