I have already generated SSL using infinityfree SSL tool , issued, and uploaded Private Key and Certificate. But when I entered the site(using https), it showed this error “ERR_SSL_PROTOCOL_ERROR”.
use Cloudflare, set to Flexible wait for 1 day or more and it will automatically fix and add Lets Encrypt. Then install Cloudflare plugin on Wordpress if you use wordpress (You can access website admin via Samsung Internet default browser)
@R0ot3dDr0id, The site is working fine with SSL, Cloudflare is not required to solve this. It is a cache issue. Your phone works because it has not cached the site yet, not because it is a Samsung.
@huacat1017, note that your ISP may also cache the site. Use a cellular device on a cellular network (And clear is cache first as well), or use a different internet.
The problem is back!
How to clear the ssh cache in my Internet Provider?(I have tried to clear browser / SSH cache in my computer)
I have to use a new network or a new computer to solve that problem.
