WordPress multisite causing Error 101 (net::ERR_CONNECTION_RESET): Unknown error [duplicate]

Your .htaccess and wp-config.php look fine.

Error 101 is usually caused by a network, router or proxy issue. It could also be related to your browser cache and or cookies Have you tried connecting with a different browser or computer or clearing your browsers cookies?

It can also be caused by your computers antivirus or anti phishing software which might not recognize your new site yet.

Was your home url and site url set the same in your general settings?

If they were not you can manually override them in wp-config.php

define('WP_HOME','http://example.com');
define('WP_SITEURL','http://example.com');

I can’t thing of anything else it could be.
