Help one of four Pairui drivers dimmed all of the sudden

I have been running four Pairui 250s with 20cobs for about 6 weeks with no trouble. They were fine last night when lights came on, but this morning one looks like it is dimmed way down. I did raise the light last night but it was running fine after i raised it. I soldered the DC side at the driver and wago at the cobs, i guess i will cut out my solder and wago the wires. And make sure the connections along the 5 cobs are secure. If you guys that know more than me ( which is all of you) have any ideas please let me know. I have a hell of a run going and this is going to cost me big time if i dont get it fixed fast.

are you using a dimmer knob/pot on this driver? and could it be somehow grounded out now since you raised the light?

If there is a bad connection at the cobs would they even light up at all? I used the wire cutter sent which is stranded and was a pain in the ass to get them into cob holder is why i ask.

I will check dimmer wires to make sure they are capped and all the connections at the cobs and wago the DC connection that i soldered, thats all i can think to do. I actually just placed a order with you cobkits friday or thursday, i will try to add a 250watt driver to my order now in case my pairui has crapped out.
