Hi, I am new to Activiti. I had set-up the Tomcat server and when I opened the Activiti admin (http://localhost:8080/activiti-admin) page, the tasks that I deployed are not showing in the Deployment section. I have used the credentials Username/Password as admin/admin. It shows the error, 'Unable to connect to Activiti server'. Can someone please help me with this problem?
1. Examine your logs (catalina.out, ...)
2. Verify your environment (firewall, ...)
I can't find any issue in the logs. This is the catalina log file,
