I never had any disconnects until now, but now there is one site that disconnects repeatedly. Reconnecting after deactivating and reactivating the child plugin works for a short time.
The only thing I can think of that is different to all other sites I maintain is that it is redirected to a subdirectory install via index.php:
require( dirname( FILE ) . ‘/sub.directory/wp-blog-header.php’ );
TIA for your help.
