java.security.cert.CertPathValidatorException: Trust anchor for certification path not found

[Paul92029]

When I run the Wikipedia app on my Android 10 Google Pixel 3 XL, as soon as I type the first character into the search, I get an error: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found. When I run this on my Pixel XL it works perfectly.
I think this is causing problems in other apps as well, I have a few other apps that have very strange connectivity issues.
All help is greatly appreciated!!

Welcome to Android Central! I moved this from the Android Apps forum to the General Help forum since the former is intended for developers to promote their apps.

Have you already tried clearing the app cache/data for the Wikipedia app in Settings>Apps​?

I cleared out Wikipedia's cache and data, uninstalled Wikipedia, restarted the Pixel, reinstalled Wikipedia, and I have the same error.

Go settings and check your security , make sure up to date

It sounds like it's something on the server side: https://developer.android.com/training/articles/security-ssl. But I'm not sure why it still works on the Pixel XL.

You could try going to Settings>Security>Encryption>Clear Credentials.

Yup my next step if security up to date

At a quick glance, this error would seem to suggest that your phone is missing a top-level cert from one of the cert issuers.

Thanks, this put me on the right track.

There is a list of trusted system credentials in Android, maybe like 100. About 30 of these were disabled, I believe as part of a security update? If I enable all of these, it starts working.

Some of these look a bit sketchy, I'll need to look to see if there is a recommended list.

I think the trusted credentials are ok, so you should be ok enabling them.

Yeah those settings never mess with some people try to toggle off thinking security concerns , they come with the phone no security issue.
