I'm investigating a read-only read-only connection verification timeout on our workshop laptop with Fairino FR10 in a training cell with documented read-only access, using a fixture plate as a reference. Ping sometimes succeeds. Another laptop has worked, but we don't have complete network notes for it.
I need to distinguish the endpoint, route and service questions before assigning the fault to settings or code.
Compare the recorded controller endpoint with the route each laptop selects for it, using sanitized details that omit unrelated network addresses. Do those routes differ?
@SaraChen1157 I've confirmed our script uses the recorded endpoint. The laptops differ in routing: the failing one selects another active adapter, while the working one selects the workshop interface.
Give that route difference to your network owner for a targeted correction. Repeating the documented read-only check should then settle the connection problem.
You're right about my prediction. The repeat check tests the routing hypothesis, with connection-stage failures kept separate from subsequent service or application responses.
@SaraChen1157 What weight should I give the ping results in our notes? I've several screenshots, but they haven't explained the read-only service timeout.
@LucyAbbott0045 Ping gives limited information about reachability under its own handling rules. Its success doesn't verify the SDK service, and its failure doesn't establish controller unavailability.
I'll retain the relevant adapter state alongside our selected-route information, making sure it describes the same laptop session in which the check fails.
The initial troubleshooting question has a concrete answer: our laptops select different routes to the recorded endpoint. Resolution still depends on the network owner's correction and a successful read-only check under normal conditions.
