android – SSL certificate is not trusted – on mobile only

Posted by: admin March 10, 2020 Leave a comment

Questions:

My site is working great over SSL in my desktops (chrome) I have a green lock near the address bar saying “Identity verified”

But using a mobile mobile browser (Chrome/Safari)I see the following message – “The identity of this website has not been verified” and the lock (in chrome near the address bar) has a red x mark on it
Any idea why it happens?

How to&Answers:

Put your domain name here: https://www.ssllabs.com/ssltest/analyze.html
You should be able to see if there are any issues with your ssl certificate chain.
I am guessing that you have SSL chain issues. A short description of the problem is that there’s actually a list of certificates on your server (and not only one) and these need to be in the correct order. If they are there but not in the correct order, the website will be fine on desktop browsers (an iOs as well I think), but android is more strict about the order of certificates, and will give an error if the order is incorrect. To fix this you just need to re-order the certificates.

Answer:

The most likely reason for the error is that the certificate authority that issued your SSL certificate is trusted on your desktop, but not on your mobile.

If you purchased the certificate from a common certification authority, it shouldn’t be an issue – but if it is a less common one it is possible that your phone doesn’t have it. You may need to accept it as a trusted publisher (although this is not ideal if you are pushing the site to the public as they won’t be willing to do this.)

You might find looking at a list of Trusted CAs for Android helps to see if yours is there or not.
