When redirecting with .httaccess from www to non-www, add double slash at the end of the main url

Hello!

Let's see if you can give me a hand :)

I am trying to modify the httaccess of my blog so that when they try to access through www it redirects to non-www and the fact is that I get it, but when it redirects to the home page it adds a double slash at the end, eg: https:// loquesea.com//

The fact is that with the other urls it doesn't happen to me and it's something that is making me a little desperate.

This is the rule I'm using:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.([^/]+)/$ [NC]
RewriteRule ^/(.*) https://%1/$1 [R=301,L]

With the regular expression I try to get only the loquesea.com part and I have tried doing it with code and it works perfectly so I don't know why it could be happening.

The web is made with Django, I don't know if it could be influencing something.

Thanks in advance!
