It’s important that you’re able to successfully connect your ZenPad Z8 device at all times. I’m sorry if this hasn’t been your experience with your device lately. I would love to help.
Can you provide a little more details on exactly what you’re experiencing with the connection port on your tablet device? Are you trying to connect your wall charger to your device? Will the charger work with any other device? Can you check the charger or cable for any physical damages as well?
