In the [General Architecture](https://community.denodo.com/docs/html/browse/7.0/solution_manager/administration/general_architecture/general_architecture) of the Solution Manager, it shows that Soluion Manager has its own Virtual DataPort Server for authentication purposes. So putting Solution Manager together with your primary Virtual DataPort Server on the same machine will create some issues with port numbers and resource data.
I believe, based on your question, that this may be the issue. I would also recommend you look at the port numbers in Solution Manager and see if those ports are not being used elsewhere on the machine.
Hope this helps!
