Problem: When using mobile app you receive the error "Failed to load scopes from access point. Error."
Solution: This can happen if you don't have the correct IP range configured.
- Go to Configuration → Remote Access → Expand Remote Access.
- Under 'API Allowed Networks' make sure that the correct IP range is in use or try using an * which means allow all.
- Also check that the 'enable mobile site' check box is checked.
- Also set internal and external URLs.
