Android release can't connect to https

When i try to connect to https url in debug mode (on device) it works great. But after create release version https connections won’t work (http is ok). Is it some trouble with whitelist? I’ve got
<access origin="*"/> <allow-intent href="http://*/*"/> <allow-intent href="https://*/*"/>
in config.xml. User can define his server url, so I need to allow for all connections.

Check the SSL certificate is set up properly, sometimes it will show the green padlock in some browsers but still not be set up properly (e.g. if an intermediate certificate is missing):

Run it through a tool like this to check:

Hi. Thanks for your reply. Probably it’s a problem with SSL certificate - we are using wildcards on our server.
