Android Question Trust anchor for certification path not found.

Juzer Hussain · Jul 19, 2021

Hi Erel,

Since i have updated to B4A 11.0 jobs are failing.
shows Trust anchor for certification path not found.

I searched forum and added conditional parameter HU2_ACCEPTALL in build configuration window but it throws error, For HU2_PUBLIC it doesn't give error but job still fails saying
Trust anchor for certification path not found.

Can you pls guide.

Manifest -:

B4X:

AddManifestText(
<uses-sdk android:minSdkVersion="21" android:targetSdkVersion="28"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)

Thanks
Juzer

In manifest

B4X:

AddManifestText(
<uses-sdk android:minSdkVersion="21" android:targetSdkVersion="28"/>
<supports-screens android:largeScreens="true" 
    android:normalScreens="true" 
    android:smallScreens="true" 
    android:anyDensity="true"/>)
SetApplicationAttribute(android:usesCleartextTraffic, "true")

Pls reply.

HU2_PUBLIC has nothing to do here.
HU2_ACCEPTALL works as it should.

The error you get has nothing to do with the certificate and is also not related to B4A version.
You need to check the server logs or check the server documentation to find out why your request is rejected.

OK Thanks Erel
I will check.

Hi Erel,

Just to confirm site settings i created a new project with source files of HttpUtils2Service and HttpJob added.
The job gets completed without any issue.

I removed Conditional Symbol in problem project and added the same 2 source files
I get following error
ResponseError. Reason: javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found., Response:

The manifest entry is same in both projects.

This means site settings are not the issue.

Pls give some clue.

Thanks
Juzer
