ERR_TOO_MANY_REDIRECTS after installing defender plugin

Getting ERR_TOO_MANY_REDIRECTS error while trying to access wp-login.php and wp-admin after installing defender plugin.

Only occurs over the main site which has the security certificate installed. Were running a multisite and do not have a wildcard SSL installed at this point just a standard SSL on https://www.sitewyse.net

Tried deactivating the plugin but the issue has continued.

Can login to the site using http://www.sitewyse.net/pro-site which opens up an alternative login page.

Have checked the wp-config and site url in the database is set as https://www.sitewyse.net

Have disabled..

// define(‘FORCE_SSL_ADMIN’, true);

in WP-CONFIG

Have cleared cookies and the same problem persists

Can login to sub sites using the http non ssl subdomains.

Using LE Lets Encrypt SSL

.htaccess file..

# Allow LE access to .well-known directory

RewriteRule ^.well-known/(.*)$ – [L]

# BEGIN WordPress

<IfModule mod_rewrite.c>

RewriteEngine On

RewriteBase /

RewriteRule ^index.php$ – [L]

# add a trailing slash to /wp-admin

RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]

RewriteCond %{REQUEST_FILENAME} -d

RewriteRule ^ – [L]

RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

RewriteRule ^(.*.php)$ $1 [L]

RewriteRule . index.php [L]

</IfModule>

# END WordPress

Options -Indexes

Have tried removing defender entries on .htaccess.. doesn’t make any difference.

Any suggestions help appreciated..
