Did it just start leaking or new install? Is the o ring still on it. How tight is the nut? Is there already sealant in the tire? Did you spin the tire around after installing sealant?

If it is a new install, the majority of valve leaks are a sign of bad rim taping

Turn the nut tighter. If that don’t work. Take off one bead of the tire at the valve. Remove the valve. Clean all mating surfaces and make sure the rubber at the base of the valve isn’t cut. Reinstall everything and air it up. If it still leaks replace the valve

If it has been more than 3-4 months since you refreshed your sealant, it may simply be that. Check if the valve lock ring is tight enough. If the sealant is good, and the valve is tight, your problem is the tape or the valve base/ o-ring.

Remove the valve core and clean it though you can get a bag of replacements for a few bucks. Usually easier to just replace the core.
Sealant gums up the core so it can’t seal all the way.

Once all the air has been removed from the tyre, you won’t see any bubbles out the valve..
I’ll see myself out..

Check the rim tape/valve rubber gasket. I’ve had both fail on me before on a new setup
