Lost wp-admin access after https change, help

I used certbot to get a cert for apache and then changed the url in WP settings from http to https. This caused the following error:
Error code: SSL_ERROR_RX_RECORD_TOO_LONG
I changed wp-config.php with

define( 'WP_SITEURL', 'http://mysite:8080' );
define( 'WP_HOME',    'http://mysite:8080' );

and that allows me to view the page but any attempts to access the admin page gets redirected to https and results in the error again. How do I manually change back that General Settings option without the UI??
