Recessed lighting not working with new LED light bulbs. Please help.

I have the old can pot lights in my basement and switched all of the old halogen bulbs to LED light bulbs (BR 30s). For whatever reason, 4 of the 20 of the recessed lights didn't work with the new LED lightbulbs, this is also after trying multiple bulbs to see if there was a defect with the bulb itself .... Anyone know why this is happening? And why is it only lighting up with the old halogens only?

One possible reason: lightbulbs need to make contact with the metal threads and the thin metal strip at the "tip" (the "hot contact" in the photo below). Sometimes this metal strip gets compressed and doesn't make contact with certain bulbs. Turn off the circuit breaker, then use pliers, etc. to pull the metal strip downwards to ensure it'll make contact with the tip of new lightbulb.

Perhaps the old bulbs had a longer "tip" than the LEDs, so it wasn't a problem in those specific cans

Are these lights on a dimmer? The dimmer may not be rated for LED or the bulbs may not be rated for dimmer use. Weird things can happen with LED bulbs and dimmers. Even if the bulbs are dimmer rated and the dimmer is LED rated there's no guarantee they work together.

If there is a dimmer I'd turn off the breaker, swap the dimmer to a standard switch and try that. It can at least help to rule out if that is your issue.

This is a good tip. I'll try to pull the metal tip down tonight.

Yes I've encountered that challenge before however these cans are all wired to a standard switch. Though thank you for replying.
