SSL works in browsers, but application still shows SSL error

1

Hello,

We have configured SSL on our server and verified that it is working correctly.

  • The website opens without any certificate warnings in all major browsers

  • The SSL certificate and chain are properly installed

  • SSL checks do not report any errors

However, the application (Survey Solutions app) is still showing an SSL-related error and does not work as expected.

Could you please advise what might cause the application to report an SSL error even though the SSL configuration itself appears to be correct?

If needed, we can provide:

  • Server configuration details

  • Certificate chain information

  • Error messages or screenshots from the application

Thank you in advance for your help.

What Andoid version is on device?

Could you try a different device (supported by Google Android version 13+)?

Our tests displays that server side looks OK.

Dear friend,

I had a similar issue before. Could you please check the certificate chain on your side and make sure all certificates are correctly declared (CA and intermediate certificates), especially if you are using a proxy?

For testing purposes, you can try the application on a local Wi-Fi network without passing through the proxy.

You can also use online DNS/SSL check tools to verify whether the SSL certificate chain is correctly configured.

This was the cause of my issue when I faced a similar problem.

Wish you good luck.

Best regards,

That’s what the following was about:

In all likelihood the server is using a correct certificate, but obsolete devices don’t trust it.
