Wp- admin redirect loop

My Site https://fyitransition.net/,
is redirecting my wp-admin attempts to https://fyitransition.net/wp-login.php?redirect_to=http%3A%2F%2Ffyitransition.net%2Fwp-admin%2F&reauth=1 this redirect page.

NOT FOUND it looks like etc…

I have combed through maybe 30 posts on here and another 20 on stack to no avail.
Ive renamed the plugins folder.
Ive cleared my cookies.
Ive installed A BRAND NEW 3.9.1 to a new db only to get no love . It didnt generate the htaccess so it gave me a forbidden message , just like when i clear the ht access altogether.
Ive tried removing and modifying htaccess , purging the rewrite in phpadmin, changing the url in options and countless other things and still cant get into my backend.

Im not versed in wordpress, php or any coding but I can fiddle around with stuff and have had this happen on another site before and actually fixed it.
this time , not so much.
I hate asking for help , but its time to reach out.
this is my htaccess:

# BEGIN WordPress

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule  /wp-admin/ /wp-admin/index\.php [L,P]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress`

as you can see Ive added a few lines suggested by others who were successful with their repair , so meh.
Im tired and hopefully someone can help me here .
Thanks In Advance
