I've got a Nexus 7 tablet with Android 4.4.2 and browsers Chrome and FireFox installed on it. When I open the website https://ib.sb24.com with it, it prompts me that the certificate is not trusted but when I open the same address with a desktop browser it's alright! Why is that?
[UPDATE]
By desktop I mean Windows and Ubuntu, Chrome and FireFox.
This looks like the server is configured wrong. It only sends a single certificate which is not signed by a known root, but instead by an intermediate CA. But the server forgets to add the needed intermediate certificates too.
The reason it works in your browser that you once browsed a site where the same intermediate CA was used and the browser cached the CA. Probably all browsers do that to help with such misconfigurations, but this does not help if the browser never visited a properly configured site with the right intermediate CA before visiting the misconfigured site.
If you don't believe me try to visit the same site with a fresh firefox profile, you will get the same problems.
Chrome most likely uses platform native store/list of trusted root certificate authorities therefore root CA which is trusted on your desktop platform (i.e. Windows) may not be trusted on Android platform.

Having an issue with my SSL certificate. Often it seems to work fine, but sometimes the user's browser throws up a warning that it is not trusted.
I know very little about SSL certificates, but here is some information that may or may not be relevant:
URL: demo.EnterpriseJazz.com
It is a wild card certificate because
the application uses subdomains (one subdomain per registered organization Example: BobsLawnCare.EnterpriseJazz.com)
The certificate was cheap for a wild card certificate, I paid around $50 for it if I remember correctly. I believe I got it from a cheap re-seller.
The server is located in my house on a Verizon FIOS business internet connection. It is not in a data center.
Seems to work fine with:
Safari on my new Macbook Pro
Chrome on my new Macbook Pro
Firefox on my windows machine
Microsoft Edge on my windows machine
Internet Explorer on my windows machine
Opera on my windows machine
Firefox on my Linux machine (CentOS)
Not trusted with:
Chrome on my iPhone 6s
Safari on my iPhone 6s (screen shots below)
Have a look at the SSLLabs report for this site. Apart from a shockingly insecure setup you will notice:
This server's certificate chain is incomplete.
This means that the client has not enough information to build the trust path to the root certificate and thus can not accept the certificate as trusted.
However a desktop browser will attempt to work around such setup problems by trying to fill in the missing chain certificates, i.e. downloading these from the web or using cached certificates from earlier connections to other clients. But apart from the desktop browsers most other clients will not do it and thus fail.
I had the exact same issue.
After futzing with every nook and cranny of my SSL and http setups, I finally realized "How silly I was to not check the URL first!"
My browser had been connecting to the regular non-trusted site (http://example.com) and I had blindly assumed that the broken lock icon meant something was wrong with my cert installation. Duh!
Modern browsers hiding the actual protocol letters behind a pretty icon or user-friendly message that conflates two issues into one - that didn't help.
My suggestion would be to first make sure you're hitting the https version of your site. If not, your first step to the solution is to create an automatic redirect of all http to https.
I hope getting to this post first helps at least 1% of those who had this problem. I'm in that 1%
at the same(=identical) youtube url I get three different messages (see attached picture). Video is available for IE and Chrome. Most puzzling to me is that I have a private key of certificate for the server (IE version). I probably do not understand something.
Internet Explorer: Microsoft Family Safety is known to intercept SSL connecitons. That's why you see the certificate for google signed by Microsoft Family Safety and because the private key for the certificate is needed for SSL interception you see that the private key is available on the computer.
Firefox: Firefox uses the system proxy settings and thus is also subject to SSL interception. But Firefox does not use the systems CA store and thus the CA for Microsoft Family Safety is not trusted by Firefox. That's why you get the error.
Chrome: Chrome uses the systems CA store and should also use the systems proxy setting by default. But the picture shows that Chrome gets the original certificate. The only explanation I have for this is that this snapshot was either done on a different computer with different setup or that the settings of Chrome were changed so that it does not use the system settings any more.
recently I was working with some facebook api and programs, and I upgrade my windows 8.0 OS to windows 8.1 OS and when I run the program I get this errors in IE11.
Content was blocked because it was not signed by a valid security certificate.
For more information, see “About Certificate Errors” in Internet Explorer Help.
how can I solve certificate issue? "how to add certificate if needed"
Open IE Tools > Internet Options > Content tab, then select the Certificates button. From there you can go through the applicable Cert types including:
Personal
Other People
Intermediate Certification Authorities
Trusted Root Certification Authorities
Trusted Publishers
Untrusted Publishers
As you mentioned "working with some facebook api and programs" check in the Untrusted Publishers section.
You can also right-click on the Windows icon and select Run, then type: certmgr.msc and go through your certificates in there as well.
Working with a ticketing system site that must be accessed via HTTPS at https://www.threestages.net
Our images are hosted elsewhere ( https://wserver.flc.losrios.edu/~vapa/) and also accessed via HTTPS.
We have multiple reports that Safari 4.1.3 on Macs is not displaying the images. We have no reports of this behavior from any other browser or platform.
Any one have any notion what that would be about?
Thanks for any thoughts,
JG
So it turns out that Safari has an issue with the SSL Cert at https://wserver.flc.losrios.edu/
http://www.sslshopper.com/ssl-checker.html let me know that
The certificate is not trusted in all
web browsers. You may need to install
an Intermediate/chain certificate to
link it to a trusted root certificate.
Thanks for looking at this. Valuable lessons learned:
Even if 4 out of 5 browsers accept an SSL Cert that doesn't mean they all do
Just because the sysadmin says it's not his problem/mistake doesn't make it so!
Check everything. Then repeat.
Could you answer to at least one of these questions:
1) Is godaddy SSL standard certificate compatible with all browsers (chrome and safari on iphone, or android browsers included) ?
http://www.godaddy.com/ssl/ssl-certificates.aspx?ci=8979
2) Is it running on Apache servers ?
Those particular certs claim to have 99% Browser Recognition.
I think that's pretty high but I have found the Godaddy certs to be pretty good.
Remember they are probably not including mobile browsers in this statistic.
Also have you checked out this page as they are cheaper?
