2019-12-04 17:03:25,404 ERROR [alfresco.web.site] [http-nio-8080-exec-31] javax.servlet.ServletException: Could not resolve view with name 'activiti-app' in servlet with name 'Spring Surf Dispatcher Servlet'
1.) you are following the guide for activiti enterprise edition (APS), follow this for community 6.0.0
2.) after war deployment (if everything goes right) your url should be something like - https://gi.processoverde.com.br/activiti-app since both are separate webapps - this gives 404, check if your deployment was correct, and the activiti-app is being started properly in catalina logs
