After installing ArcGIS Monitor 2025.0 , the monitor home page does not load up.

Have installed ArcGIS Monintor 2025.0 on couple of machines. Post installtion the ArcGIS MOnitor home page doesn't load up. 

Has anyone faced similar issue?

In one of the box I have insatlled POSTGRES 15.13 and on another 16.9.

Hi @SatishNaik1 

Sorry to hear you are having this issue. 

Can you check permissions for the monitor service account in the key directories: 

C:\Program Files\ArcGIS\Monitor
C:\Users\<MonitorAccount>\AppData\Local\ESRI\ArcGISMonitor

Are ports 30443 for HTTPS or 30080 for HTTP closed? 

Another few things to run through and check:

1. Check if the Monitor Server service is running via Windows Services.
2. Run Monitor Server in debug mode to identify startup errors:

Powershell
$env:LOG_LEVEL='debug'
.\arcgis-monitor-server.exe --serve

3. Verify DNS resolution:
• Run nslookup <server IP> and ensure it returns a valid domain name.
• If it fails, configure reverse DNS or update your local DNS settings.
4. Ensure required ports are open (30443 or 30080).
5. Check PostgreSQL logs for connection or schema errors.
6. Reinstall or reconfigure Monitor if .env or config-store folders are corrupted.

Here is documentation and a previous ArcGIS Monitor posts
