Before you contact Support, please check this list of common error messages and our suggestions to troubleshoot them.
Invalid authentication method

- It's common to see this error if you've attempted to access a workspace or model using an incorrect login method (for example, with an Anaplan login rather than single sign-on).
- Support will advise you of the correct login method.
Transport exception

This error could be caused by:
- Brief, local connection problem
- Larger network connection problem
- Browser issues
Troubleshooting:
- Check internet connection.
- Clear browser cache and cookies.
Insufficient memory to open model

This error may occur when opening a model and the total amount of memory in use exceeds 130 GB.
Typical causes:
- Too many models open at the same time (same or different workspace)
- Large imports or processes using memory (as importing data isn't accounted for in the model size before import)
Rollback
- Rollback: model rolling back to a last-known stable/good state because the attempted process isn't accepted by Anaplan.
- Rollback error: displays the blue toaster icon to users in the workspace.

- Primarily caused by incorrect formulas — a long formula may have a rollback that locks up a workspace.
- In the event of repetitive rollbacks, the workspace may become locked and Support will need to unlock it.
