When attempting to login to the VNA UI, nothing shows up:
Testing access via a REST GET query results in a Successful response, indicating that the browser is the problem:
Old Browser version not compatible with the latest versions of Swagger API
DX NetOps Virtual Network Assurance Release : 21.2
Update the browser (Firefox or Chrome) to the latest version so that it is compatible with the current Swagger API used by VNA to generate the UI in the browser.
