Perhaps try to change your current SSL Cipher with these:

https://mozilla.github.io/server-side-tls/ssl-config-generator/

I made the change, but the problem continues

No error from my end. I’m using Safari and Chrome on iPhone. Did you try to clear your browser cache?

I already cleaned the cache and the problem still
