android - Trust anchor for certification path not found with okhttp -


so i've been trying night make work, nothing seems trick ... keep getting trust anchor certification path not found.

here how i'm build okhttpclient (i followed https://medium.com/@sreekumar_av/certificate-public-key-pinning-in-android-using-retrofit-2-0-74140800025b)

fun provideokhttpclient(): okhttpclient {     val httpclientbuilder = okhttpclient()             .newbuilder()      val logging = httplogginginterceptor()     logging.level = if (buildconfig.debug)         httplogginginterceptor.level.body     else         httplogginginterceptor.level.none       val certificatepinner = certificatepinner.builder()             .add(host, sha)             .build()      val connectionspec = connectionspec.builder(connectionspec.modern_tls)     connectionspec.tlsversions(tlsversion.tls_1_2).build()      val tlssocketfactory = tlssocketfactory()     return httpclientbuilder             .certificatepinner(certificatepinner)             .addnetworkinterceptor(logging)             .sslsocketfactory(tlssocketfactory, tlssocketfactory.systemdefaulttrustmanager())             .connectionspecs(collections.singletonlist(connectionspec.build()))             .build() }

i got sha this: openssl s_client -connect host:port | openssl x509 -pubkey -noout | openssl rsa -pubin -outform der | openssl dgst -sha256 -binary | openssl enc -base64

and here tlsfacotry: https://gist.github.com/pollux-/fbcc74984e110bb49497faa2d0ed5ee1#file-tlssocketfactory-java

i don't why doesn't work @ point..

any appreciated!

iirc certificate pinning evaluated after certificate chain accepted.

it have full stacktrace, , host trying connect to, since possible using self signed certificate client won't accept.

try working without certificate pinning first, add in. @commonsware mentions when certificate pinning fails tells do.
