Cloud connector error java.lang.NullPointerException

Hi all,

I'm currently following Philip Mugglestone's tutorial on the Hana Academy on YouTube (SAP HANA Academy - Live3: Setup SAP HANA Cloud Connector - YouTube) to build an app running on HCP of Sentiment Analysis on Twitter data.

I had to install Hana Cloud Connector and create an account. I did it 2 weeks ago, I managed to log in with default logins (username Administrator, password manage) and change the password.

I tried again last week to connect with my own logins but it didn't recognize it. So I wanted to do it again from scratch but when I try to login again using the default logins, I have this error I can't solve : java.lang.NullPointerException :

Any ideas ?

Thanks,

Mohamed AL ANI
