One air pod not seating in case fully and not consistently charging

I'm having an issue where one of my 1st gen AirPods is not always charging when inserted into the case.

I'll be listening and the right pod will just stop while the other continues to work. If I watch the charge status on phone and the lights on case. I can see a change in the amount charged and color. I suspect poor contact in the bottom of the hole. I have tried cleaning but I really see nothing like dirt or tarnished metal that would cause a bad connection. Anybody else come across this and is their a solution?
