The same error occured on my site and the problem was that my server was not serving the Intermediate/chain certificate. Normally, modern browsers can resolve the intermediate certificate by themselves so it is optional. But some problematic browsers (like those embedded in facebook or instagram app) give this error.

You can checkout this comodo documentation to install the complete chain of your certificate:

blocks|key|3521949|text|这可能是两件事：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3521950|您站点上的|3521951|证书无效，或者可能像this中的情况一样，链在某处断开。您可以使用SSL+Labs+Server+Test分析您的域/SSL证书。由于某些原因，安卓手机中的|ordered-list-item|offset|length|3521952|设置不信任证书的颁发者(根用户)。在这台link上，他们说：|3521953|3521954|3521955|设置->安全->受信任的凭据--确保使用绿色复选标记启用它们。我把它们都启用了(可能你只需要VeriSign+Inc.之类的功能)，但是我把它们都启用了-这就为我解决了这个问题|blockquote|3521956|3521957|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/questions/31530265/facebook-android-security-error-there-are-problems-with-the-security-certific|1|https://www.ssllabs.com/ssltest/analyze.html|2|http://www.androidtablets.net/threads/solved-security-certificate-problem.56833/^0|0|0|A|4|0|X|K|1|0|K|4|2|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|12|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|13|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|14|8|@]|9|@$G|15|H|16|1|17]|$G|18|H|19|1|1A]]|A|$]]|$1|I|3|J|5|F|7|1B|8|@]|9|@$G|1C|H|1D|1|1E]]|A|$]]|$1|K|3|-4|5|6|7|1F|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|1G|8|@]|9|@]|A|$]]|$1|M|3|N|5|O|7|1H|8|@]|9|@]|A|$]]|$1|P|3|-4|5|6|7|1I|8|@]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|1J|8|@]|9|@]|A|$]]]|R|$S|$5|T|U|V|A|$W|X]]|Y|$5|T|U|V|A|$W|Z]]|10|$5|T|U|V|A|$W|11]]]]

This could be possibly two things: 

<ol>
<li>Certificate on your site is invalid, or maybe chain is broken somewhere as in <a href="https://stackoverflow.com/questions/31530265/facebook-android-security-error-there-are-problems-with-the-security-certific">this</a> case. You can use <a href="https://www.ssllabs.com/ssltest/analyze.html" rel="nofollow noreferrer">SSL Labs Server Test</a> to analyze your domain/SSL certificate. </li>
<li>Settings in the Android phone for some reason are not trusting to the issuer (root) of the certificate. On this <a href="http://www.androidtablets.net/threads/solved-security-certificate-problem.56833/" rel="nofollow noreferrer">link</a>, they say: </li>
</ol>

<blockquote>
 Settings -> Security -> Trusted Credentials -- Make sure they are enabled with the green checkmark. I enabled them all (possible you may only need VeriSign Inc and such enabled) but I enabled them all --- and that fixed it for me
</blockquote>

blocks|key|5633986|text|这很可能是由于嵌入式浏览器无法看到整个证书链造成的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5633987|如果你有中间证书，你可以很容易地解决这个问题，你只需要用ssl证书来测试它：|5633988|cat+IntermediateCA.cer+>>+ssl_certificate.cer|offset|length|style|CODE|5633989|然后用包含连接的值的新证书替换旧的ssl_certificate.cer。|5633990|entityMap^0|0|0|0|19|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|P|8|@$F|Q|G|R|H|I]]|9|@]|A|$]]|$1|J|3|K|5|6|7|S|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|M|$]]

This is most likely due to the embedded browser not being able to see the whole certificate chain.

You can easily fix this if you have the intermediate cert, you just need to cat it with the ssl cert Ex:

<code>cat IntermediateCA.cer &gt;&gt; ssl_certificate.cer</code>

Then replace the old ssl_certificate.cer with the new certificate containing the concatenated values.

blocks|key|5634023|text|我在一个网站上遇到了同样的问题。我花了一段时间才弄明白。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5634024|如果您尝试通过https://方案访问url或资产文件，但ssl在该域上不起作用，请签入代码。|5634025|在我的特殊情况下，www.{domain}+ssl显示了这个错误，因为一些标签有来自旧的"cdn“子域(https://q.{domain}.com)的src，并且这个子域的.com不起作用。|offset|length|5634026|这与网站的url或www版本没有任何关系。|5634027|entityMap|0|LINK|mutability|MUTABLE|url|https://q.{domain}.com/^0|0|0|1G|M|0|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|S|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$F|U|G|V|1|W]]|A|$]]|$1|H|3|I|5|6|7|X|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|Q]]]]

I had same issue on a website. Took some time for me to figure it out.
Please check in code if you are trying to access a url or asset file via https:// scheme and the ssl is not working on that domain.
In my particular case, www.{domain}.com was showing this error because some tags had src from old &quot;cdn&quot; subdomain (https://q.{domain}.com) and this subdomain's ssl was not working.
it had nothing to do with site's url or www version of site.

I had the same problem with Instagram and Chrome on Android.
I used SSL Let's encrypt - first I deleted all the certificates - and changed the SSL/TLS KEY TYPE from SSL/TLS in cPanel from - ECDSA, P-384 to RSA, 2,048-bit -you can manual generate new key or Auto install SLL and works fine

Some users get this error when viewing the link in the Android Facebook Browser. Our SSL is current and active. And it does not happen on desktop browsers or in the ios Facebook App.
