Hello

i’m still struggling in making the webrtc feature. 1st thing i notice is apparently there is a keystore error:

the command keytool -list -v -keystore /usr/local/WowzaStreamingEngine/conf/xxxx.streamlock.net.jks

returns the following error:

erreur keytool : java.io.IOException: Invalid keystore format java.io.IOException: Invalid keystore format at sun.security.provider.JavaKeyStore.engineLoad(JavaKeyStore.java:650) at sun.security.provider.JavaKeyStore$JKS.engineLoad(JavaKeyStore.java:55) at java.security.KeyStore.load(KeyStore.java:1214) at sun.security.tools.KeyTool.doCommands(KeyTool.java:789) at sun.security.tools.KeyTool.run(KeyTool.java:340) at sun.security.tools.KeyTool.main(KeyTool.java:333)

any idea about what the problem is and how to solve it ?

thanks !
