Diagnosing between two machines

Find the faulty side

The lab-node1 table is clean now, yet the site fails to open again — and the failure looks different from the start of the lesson.

Find the machine with the fault and fix that one alone. Leave what works untouched: the addresses and connected routes of both machines must stay as they are.

Find the side and fix the path

The site 192.0.2.12:8080 again does not open from lab-node1, although the lab-node1 table is fine now. Find which machine has the fault and fix it so that /health answers from lab-node1. Leave the addresses and the connected routes unchanged.
