问题
I am studying IOT-server. I have a question and please help me.
I use WSO2 IoT server and I am not able to access WSO2 IoT server device Management Console (https://localhost:9443/devicemgt) when I input 'admin' both username and password or input this which created a new account.
As a result, it showed me the Authentication failed. When I saw users list in https://localhost:9443/carbon, it showed admin, new accounts .... etc.
I don't know why it does not log in WSO2 IoT server device Management Console.
Please give your advice and then thank you so much.

You need to check Java version, All wso2 Products have issues with the latest version of Java, if you are using java version "1.8.0_151" then that's a problem, try using java version "1.8.0_144".
If you cannot change java version then you need to change the compression parameter to off in catalina-server.xml file
