Thanks, the ohms is between 0.03 to 0.45.
.03 is close to being a hard short... .00 is a hard short. There's no margin for error in this, which is likely why the mod isn't reading the atomizer... a regulated mod is designed so that it won't fire in a danger zone like that.
If your fluctuating between .03 and .45 on the same coil, there's something wrong with the coil or how its mounted.
Try replacing the coil with a new one, and make sure that it's mounted properly, you've screwed your leads in tightly and the coil isn't touching a metal surface (like the deck or the posts)
You might like an ohms reader to check your ohms levels... I have a coilmaster 521 mini tab and it works beautifully as a build deck and to check my ohms levels... I found mine on a sale for 8.99, but even regular price is only 20.00..
Here element vape has one in stock:

Smok as a brand doesn't have consistent quality control... so its not reliable enough to trust in its accuracy, but with that kind of a swing in ohms, and you being a new builder, it could very well be user error so it's good to try another coil just to see...
