I wrote code in android for connecting to server with ssl, I use BKS algorithm, I can create socket but when I send data to switch, I get this error javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found. It is wonderful for me, I can connect to another server in local network with another BKS file and I can get response from that server, but with correct certificate in outside network, I cannot connect to another server, is it possible with network problem? Best regards
