The referenced how tos are good. So here is a list of hidden gotchas in CAN. Avoid them, follow the how tos & it works well. Other feel free to add to the list.

Bad wiring- make sure your cable connections are good. This includes crimps in the plug & the female connector on the Jag. Do not have strain on the connectors, but don't let the wiring flop loose either.

Use terminating resistors. I not sure this is really needed in the short cable runs, but why tempt fate. Besides the first on the list of troubleshooting is to check the wiring.

Avoid running can comm cables parallel to power wires, especially motors.

Do not flood the canbus with commands. You can fill the bus up and have data drops. Make sure the programmers understand what the Jag really needs.

Do not send commands to non existing Jags. The comm driver does not like that.
