It sounds like you have a broken CAN chain. If nothing beyond the first node is seen, you have a good place to start checking. Broken chains will let you see up to the break, as long as your termination is good on the serial connector.

Look into each and every RJ11/12 port, and make sure that the contact wires are not stuck in a retracted position. If any are overly compacted, use a dental pick to VERY CAREFULLY stretch them out to a position that will ensure good contact when the CAN cables are inserted.

Not knowing the source of your CAN connection cables, you may want to check all of them, to make sure they are constructed correctly. We've had students shift wires by one position, or reverse the plug, when un-monitored. This is something that is simple enough to check, and could provide a moment for instruction.
