Trying to pinpoint a very slow ac refrigerant leak

[Christopoli]

Hello, I'm trying to pinpoint a very very slow ac refrigerant leak (charge lasts approximately 1 month). I'm not entirely sure where it's coming from, I've checked with a uv flashlight, but couldn't see any dye near any point that'd make sense. I've replaced the compressor and some o rings by where it connects to the condenser, just wondering what the cause is likely to be..?

I suspect the air conditioner in the cabin. It is usually hard to see the dye in those places, but they will lose gas over time. If you smell a slight chemical smell when you turn on the AC, it is almost certainly there.

I found out it was leaking from the low side service port valve, replaced both of them, no leaks thusfar, but we'll see. tbh i should've checked that first lol. definitely no refrigerant smell in the cabin.
