Front Gate is showing Err 3 code, which is photocell, DEA motor and was all working this morning

afternoon all Ive had nothing but issues with my gate since it was installed a couple of years a go, but today it opened fine then wouldnt close, its showing a Err 3 code which seems to be photocells, ive checked those and they have not been hit or moved, one side of the gate the sensor has a red light the other has no light, could it be a power issue to that sensor. How would i check its getting power. I'm sure it use have a red light on the other side aswell.

I actually switched it off at the electrics and on again, and it worked and opened but then showed the error message again

just for someone thats in the same situation, i managed to put another wire in across the driveway fro one sensor to the other and it works, so its the wiring, the trouble is the wiring under the driveway. I've seen that they have battery operated photocells which i will try to get then i don't have to worry about the wire.
