Redirect on m.altalanadi.tld

[Mannuel]

Hello, I want to redirect my site to mobile devices as m.altalanadi.tld using the following WordPress .htaccess code:

```

I have created a subdomain, and the subdomain is working on desktop, but on mobile, I am getting too many redirects error. How can I solve this issue?
