Hi.! I’ve had that issue also. I ended up solving said issue by these steps.:
1.) Place both AirPods into the case and close case. Let sit for 2-3 minutes.
2.) While waiting, go into your Bluetooth settings and click on the name of your AirPods. Scroll down and hit forget device.
3.) Turn Bluetooth off and then back on.
4.) Open AirPods case and hold that button on the case for about 15 seconds.
5.) The name of your AirPods should pop up under “scanning for devices”.
•If that didn’t work, try these.
Try a full reset:

Good luck, my friend. Hope I could help.
