MPPT 450/100 False BMS error 67

Getting false reports and causing complete shut down on inverter side of system it will repeat this error in a loop about every 15-30 mins.

Victron 48v/5000 inverter

18 270w panels

victron 450/100 MPPT

Lithionics 51v 630ah battery bank

Lithionics is tied to the Cerbo via VE CAN. VE Can network setup as RV-C

This issue has happened ever since doing the 1.11 firmware on the 450/100. Is there any way to revert the firmware back to 1.10 or 1.08. I looked on the victron page to find the older firmwares but do not see any previous firmwares listed for the solar controllers.

See attached.

Although if the whole system is shutting down I would wonder how often the BMS is sending a signal? The GX will give that error usually after quite a few minutes of no contact.
