I've looked through previous strings where other community members have changed their admin URL in the Magento admin panel.
After the change they get 404 error for the new URL path.
I've changed the env.php file:
return [ 'backend' => [ 'frontName' => 'magento' ],
Then I ran:
php bin/magento cache:clean php bin/magento cache:flush php bin/magento indexer:reindex
Any advice would really help, I still can't access my dev site.
Thanks so much all.
