'Could not validate certificate signature' error (Antennapod, Gingerbread) I am using Android 2.3.6 (Gingerbread) and AntennaPod Version 0.9.9.5.

When I am trying to access gpodder.net, either to login or search podcasts, I get the following
error message:

An error occured:javax.net.ssl.SSLHandshakeException: org.bouncycastle.jce.exception.ExtCertPathValidatorException: Could not validate certificate signature.


I tried to clear the cache, the data, and ultimately uninstall and reinstall the app from the Play Store, but the problem persists.

Any hints about what I can do here?
There is nothing you can do, except making your device not use ssl. Either there's a problem with the website, or a hacker is modifying your connection to the website on-the-fly but has problems.
