Issue/Introduction
The webtomcat WebApp is configured to use the default http port 9443 and to use port 8443 for SSL. However, we are not able to launch the WebApp.
As a test, we configured the WebApp to use the Linux default http port 8080 and we are able to launch the WebApp successfully.
Unable to launch the OneClick WebApp
Environment
All supported Network Observability DX NetOps Spectrum OneClick WebApp releases
Cause
Firewall rules are blocking TCP ports 9443 and 8443, which are required for WebTomcat and SSL communication.
Resolution
To properly resolve this take these steps:
- Identify the ports used by the WebApp (default 9443 and 8443).
- Verify connectivity using a test on an open port (e.g., 8080).
- Work with the security/network team to whitelist ports 9443 and 8443 on the firewall.
After opening these ports, the user will be able to launch the OneClick WebApp successfully.
