Too many redirects

I am having the problem of too many redirects on a protected folder. I have looked at previous forum threads on this topic and have tried things like clearing cache, different browsers and devices but no luck.
Below is the htaccess code :-
########### AMEMBER START #####################
Options +FollowSymLinks
RewriteEngine On

# if cookie is set and file exists, stop rewriting and show page
RewriteCond %{HTTP_COOKIE} amember_nr=([a-zA-Z0-9]+)
RewriteCond /home/clanga8/public_html/amember/data/new-rewrite/%1-9 -f
RewriteRule ^(.*)$ - [S=3]

# if cookie is set but folder file does not exists, user has no access to given folder
RewriteCond %{HTTP_COOKIE} amember_nr=([a-zA-Z0-9]+)
RewriteCond /home/clanga8/public_html/amember/data/new-rewrite/%1-9 !-f
RewriteRule ^(.*)$ https://www.clangalbraith.org/amemb...{QUERY_STRING}&host=%{HTTP_HOST}&ssl=%{HTTPS} [L,R]

## if user is not authorized, redirect to login page
# BrowserMatch "MSIE" force-no-vary
RewriteCond %{QUERY_STRING} (.+)
RewriteRule ^(.*)$ https://www.clangalbraith.org/amemb...EQUEST_URI}?%1&host=%{HTTP_HOST}&ssl=%{HTTPS} [L,R,B]
RewriteRule ^(.*)$ https://www.clangalbraith.org/amemb...%{REQUEST_URI}&host=%{HTTP_HOST}&ssl=%{HTTPS} [L,R]
########### AMEMBER FINISH ####################

I used Chrome web developers tools to try and track the loop and here is what I get :-

amemberdocs/
9?url=/amemberdocs/%3f&host=www.clangalbraith.org&ssl=on
new-rewrite?f=9&url=%2Famemberdocs%2F%3F&host=www.clangalbraith.org&ssl=on
amemberdocs/
(repeated etc.)

Can anyone suggest a fix please.
