Issue with Co2 paintball tank install

Hello everyone,
I just received my mini regulator (Aqualabs) and started installing it on my paintball tank. I'm running into an issue that I can't seem to resolve.
So I basically followed the UNS install that I found here : and did everything exactly the same. However when I screwed in the regulator with the paintball adapter to the tank, nothing happened. I tried to tighten it up and then it started hissing and co2 was evaporating loudly between the paintball adapter and the regulator. If I unscrew it a bit less I end up having a bit of pressure without any hissing sound but can't go any higher than 0.2. Any advice?
Thank you

Maybe you're o ring is bad? I had the same trouble with the two canisters I use. Each time I unscrewed my regulator, the threads would put a small nick in the o ring, causing it to leak. I bought a package of universal o rings from amazon. Problem solved for me.

I figured it out, it was the paintball adapter that was faulty. Thank you though!
