These support pages should help with troubleshooting:

If your iPad won't charge – Apple Support

Troubleshooting generally requires substitution of the Power Adapter and cable for another known-good item.

If you continue to experience difficulties, you might be best advised to visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to test and assess your iPad, Power Adapter and cable(s):

I have been struggling with the same issue for the last few days, and tried the same things you did. Finally, updating to iOs 15 fixed the problem. Is this a new sneaky way to force us to use the new iOs? Fortunately, i had just enough power for the update.

Good luck!

The cable is another possible failure, if you’re using he same cable for your tests.
