Try using a tailor’s needle or something to clean out the accumulated dirt.

Try to clean up the usb-c port on the keyboard. It might have some debris inside, that is compacted every time you insert the plug, until you can’t compress it anymore. Then the plug starts failing.

It’s the same with charger cables for your phone.

Maybe the cable itself is broken somewhere, but you can’t see it because it’s sleeved. I’ve got the same problem with my phone charger, but at least I can see the cable being ripped apart close to the connector.

It could be that the plug is just a bit too short.

maybe get a usb cable with a longer connection

Hot take - usb-c is garbage for what should be secure connections like this. There’s nothing that hooks it into place. Happens to me all the time when I’m simply moving my keyboard, oh there it disconnects again.

Maybe some hair or dust got in there and isn’t letting the cable seat fully. Try cleaning out the port with a wooden toothpick.

Check this out. I had this issue then remembered mac made a magnet for their charger so I figured someone else probably makes those for normal stuff and sure enough, you can buy removeable magnet usb c plugs so the magnetic reciever always stays plugged in and you just swipe your cable off and on that.

Skill issue /j

Usb c port gathered some dust. Stapler pin bent with a small L usually works for me. Your mileage may vary.

Does it happen with any other cables? I had this issue (with all cables that I tried) and had to replace the daughterboard.

My coiled cable had the same problem and it used to get disconnected easily. It is a nice purple/green cable that matches my setup but I switched to a magnetic cable instead. Much more stable connection.

Have you tried another cable to work out whether it’s the cable or the socket on the board?

Try using different cable. If it is sturdy, then the cable connector might be loose.

Sure….don’t move your keyboard.
