   Hi @DaanHoogland 
   
   After having properly configuring the **host** and **management.network.cidr** I don't get Cloudstack Manager to start.
   
   I am getting the following exceptions when I restart after the changes
   
   ```

   ```
   There seem to be some kind of confusion I think the manager is trying to connect to itself before has finished the startup process.
   
   But then it mentions  "another manager".
   
   Any idea what could be going wrong?
   
   Perhaps, in the install process, I should say which is the actual manager IP.
