Nest Learning Thermostat (GEN4) Not Cooling

I replaced a PRO1 Thermostat with a Nest Learning Thermostat (GEN4), but my cooling is no longer working. Pretty sure it is a wiring issue

PRO 1 WIRING

BBlue
W/EWhite

NEST WIRING

Y1Yellow
GGreen
OBBrown
W2/AUXWhite
CBlue
RhRed

I think I might need to switch the BLUE to the OB and the Brown to the C ??
Any recommendations would be appreciated.

Thanks for the help
