J1772 extension will not work with Juicebox OpenEVSE

Hey all,
I gave up on Voltie’s transition of the Juicebox. I really need the ability the adjust my amperage and I worked with their support for weeks. All they ended up doing was making my Juicebox a dumb charger stuck at 40 amps again.
So I gave up an ordered the OpenEVSE board. It was working great and the interface is perfect. But I ran in to an issue trying to charge my PHEV. My EV charges fine in my garage. It plugs right in to the Juicebox v2 with OpenEVSE and I can adjust the amperage.
The PHEV is a different story though. I park it outside and we don’t use it much. Since it’s far away, I’ve always used a j1772 extension for it. I have one I’ve been using from Amazon that used low gauge wiring. That was my primary concern and this was one of the few (if any) that actually had 8 awg wiring.
I’ve used this with my portable EVSE and my Juicebox and it always worked fine with no issues. But when I switched to the OpenEVSE board in my Juicebox, it now won’t charge the car anymore.
Both the EVSE and the car see that it is plugged in. But it won’t start charging. If I move the car in to the garage and use the cord directly, it charges without any issues.
The only thing I thought to do was to turn off the safety features in OpenEVSE. I tried that and it had no effect. I also tried adjusting the amperage down to 8 amps to see if that would work, it had no effect. I’m not sure what else I can do.
I’m guessing there is something with a drop in ohms because of the length? But I don’t have a multimeter to check anything. I also need the 40 foot length.
Anyone have any ideas on how I can get this to work?
