Symptom
- The administration console of HANA Web Dispatcher returns a 404 error when accessed via URL.
- The error message displayed is "404 - Not found. We could not find the resource you're trying to access. It might be misspelled or currently unavailable."
- The HANA Web Dispatcher is installed on a private network, for example on AWS (HANA Express Edition).
- The issue arises when trying to configure a standalone Web Dispatcher to enable HANA Web Dispatcher access via the internet.
