Codeigniter上的Ion Auth设置

I have setup Ion Auth on my Codeigniter 3 installation as per instructions.

When I navigate to:

127.0.0.1/nightmesh/auth/login

I am actually redirected to:

http://127.0.0.1/nightmesh/127.0.0.1/nightmesh/auth/login

My .htaccess in my root directory:

<IfModule mod_rewrite.c>
RewriteEngine On

#Checks to see if the user is attempting to access a valid file,
#such as an image or css document, if this isn't true it sends the
#request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
#This last condition enables access to the images and css folders, and the robots.txt file
RewriteCond $1 !^(index\.php|public|images|robots\.txt|css)
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

Any advice on how to avoid this?
