Hello,
Yes I solved it. I Gues your issue is You can not entry in the knowage BI system. Did you check your username and password? when I had this issue, I wrote to the staff of knowage BI and they sent me an authorized username and password, then I could entry in the knowage BI system page.
But, when I had the issue, I could connect correctly MariaDB and Tomcat, when I ran the server it functioned fine, but I could not login, I mean, the MariaDB and Tomcat was fine configure but my username and password was uncorrectly. I am sure if you send an email to the staff of knowage BI, they will be send to you an authorized username and password.
Best regards.
