Troubleshooting¶
This page covers common problems that affect first-time ENP users.
I Can Open ENP But I Cannot Log In¶
Check the following:
- you are using the correct URL for your environment
- your username or email is correct
- your password is current
- your organization has granted you access to that environment
If the problem persists, contact your ENP administrator or support contact.
I Logged In But I Do Not See Any Design¶
Possible reasons:
- no design has been shared with your account
- you are in the wrong environment
- you need to create a new design first
Next steps:
- try Create a network design
- confirm with your administrator that you should already have access to existing designs
I Created a Node But I Cannot See It¶
This is often caused by view settings rather than failed creation.
Check the following:
- disable Hide non-connected nodes
- zoom out or use the focus control
- search for the node from the current layout tools
- verify the node in the Control Window tables
I Am Lost Between Topology View And Control Window¶
Use this rule:
- if you need visual context, stay in the Topology View
- if you need detailed properties, filtering, or tables, open the Control Window
If needed, review Understand the interface.
The Imported Controller Topology Does Not Appear¶
Check the following:
- the controller definition was created successfully
- the controller endpoint, port, and credentials are correct
- topology discovery completed without errors
If discovery succeeds but nothing is visible, try changing zoom level or layout and then verify imported objects in the Control Window.
A Simulation Result Does Not Make Sense¶
Common causes include:
- the wrong design is loaded
- expected nodes, links, or controllers are missing
- traffic or routing assumptions are different from what you expect
- the result is being read from the wrong table or view
Before escalating, verify the current design content and review the relevant simulation reference page under Network Digital Twin.
