错误太多重定向.htaccess Magento

I changed my website from http to https with Lets Encrytp. Now I can't access my Magento Admin console. I read that it's because of the .htaccess file.

<IfModule mod_rewrite.c>

############################################
## enable rewrites

    Options +FollowSymLinks
    RewriteEngine on

############################################
## you can put here your magento root folder
## path relative to web root

    #RewriteRule ^(.*)$ /mobiledirectoryhere/ [L,R=302]

    RewriteRule .* index.php [L]

</IfModule>

Can you tell me what I have to change? I'm not quite good in Web development.

If you are experiencing error like, TOO MANY REDIRECTS on your Magento store, then the issue is because of your .htaccess file or your cache folder.

Place a new copy of .htaccess from a fresh magento package and delete the cache and session folder as well. Then refresh and it should be good.

Or another way is,

In the core_config_data table remove the value of web/cookie/cookie_domain and set web/cookie/cookie_httponly” to 0. Clear the cache by removing the files in var/cache. Also clear the cache from Magento admin panel
