Hello I am wondering whether to buy a SSL cert from Comodo PositiveSSL or just use the free SSL given by Letsencrypt. I heard that Letsencrypt doesn’t support to opera mini browser, is that true? ---

Hi @CutaInfo, we saw a complaint about this last year at > [@Cert error in Opera Mini browser](https://community.letsencrypt.org/t/cert-error-in-opera-mini-browser/20737): > > H… I don't know where to get authoritative up-to-date information about this. If you have access to Opera Mini, you could try accessing a site (like this forum!) secured with Let's Encrypt and let us know about the results. ---

In my Android 7.1 mobile phone, Opera Mini shows a lock in the address bar when I surf to this forum. It doesn’t give me any opportunity to view any information about the state of the (secured) connection though… Strange thing: if I surf to [google.com](http://google.com), I don’t get a lock icon? ---

Thanks. checked on both UC Browser and Opera Mini (latest versions), worked fine. so I ended up installing letsencrypt in my site. Hope it won’t go wrong. 🙂 ---

@CutaInfo compatibility is a 2 stage process A) does the server serve up intermediates to create a chain of trust B) does the server support the right algorithms for compatibility In terms of LetsEncrypt vs Comodo - A) Makes no difference if you include the intermediates B) run your site through [ssllabs.com](http://ssllabs.com) - this will give you an idea of what clients are supported with your current configuration Mozilla provides a great guide on what ciphers to use: [https://wiki.mozilla.org/Security/Server\_Side\_TLS](https://wiki.mozilla.org/Security/Server_Side_TLS) Andrei ---
