Issue/Introduction

After upgrading DX Netops Virtual Network Assurance (VNA) from 20.2.7 to 20.2.9,  I am unable to access the UI link.

Error: 'Site can't be reached'.

MySql is running fine, wildfly service is up and running.



Cause


Running curl to the VNA UI ports works fine from the local server:

curl -Lv 127.0.0.1:8080/vna
curl -Lv 127.0.0.1:9990

There is something blocking access to the VNA ports.

Environment

Release : 20.2

Component : Virtual Network Assurance For CA Spectrum

Resolution

Verify if any firewall rules/devices are blocking access to the VNA ports or if there are intermediate network issues.
