CANBUS cable

So I have been back and forth with a Chinese company (cough-BestGo-cough) about a charger that won't pick up the message to begin a charge cycle. My BMS is getting the CAN message and I can see the CAN message going to the charger. My BMS support has pointed out that not all CANBUS transceivers are created equal. I suspect that my cheap Chinese charger has a cheap transceiver and is unable to pick up the messages over my dirty cable. I have chopped the stubs to only 8" and have soldered all my wire connections. I have a BT scan tool that is working okay with Torque. All my communication with my BMS is over the CAN which works fine too. I can actually see the message from the charger that shows the communication failure. Does anyone have a special technique to build a solid CANBUS cable that might help resolve my cheap charger issue? Evidently, the charger won't work unless the CAN message is received by the cheap charger transceiver... lesson learnt, buy American.

I know there's some problems with Elcon... Maybe this is similar?
