java - Random javax.net.ssl.SSLExceptions using OkHttp client -

-

in android app using okhttp client trusts ssl certificates. problem is, facing random sslexceptions. example 8 out of 10 calls fail due sslexceptions , 2 succeed.

any pointers on why might happening? please let me know if need more info.

stack trace:

this how create okhttp client:

private okhttpclient getunsafeokhttpclient() {     try {         // create trust manager not validate certificate chains         final trustmanager[] trustallcerts = new trustmanager[]{                 new x509trustmanager() {                     @override                     public void checkclienttrusted(java.security.cert.x509certificate[] chain, string authtype) throws certificateexception {                     }                      @override                     public void checkservertrusted(java.security.cert.x509certificate[] chain, string authtype) throws certificateexception {                     }                      @override                     public java.security.cert.x509certificate[] getacceptedissuers() {                         return null;                     }                 }         };          // install all-trusting trust manager         final sslcontext sslcontext = sslcontext.getinstance("ssl");         sslcontext.init(null, trustallcerts, new java.security.securerandom());         // create ssl socket factory our all-trusting manager         final sslsocketfactory sslsocketfactory = sslcontext.getsocketfactory();           return createokhttpclientwithtimeout(sslsocketfactory);     } catch (exception e) {         throw new runtimeexception(e);     } }  protected okhttpclient createokhttpclientwithtimeout(sslsocketfactory sslsocketfactory) {     okhttpclient okhttpclient = new okhttpclient();     okhttpclient.setconnecttimeout(connect_timeout_millis, timeunit.milliseconds);     okhttpclient.setreadtimeout(read_timeout_millis, timeunit.milliseconds);     okhttpclient.setsslsocketfactory(sslsocketfactory);     okhttpclient.sethostnameverifier(new hostnameverifier() {         @override         public boolean verify(string hostname, sslsession session) {             return true;         }     });     return okhttpclient; }

note: know trusting ssl certificates bad.
