My beacon shows attached error message. Beacon last reported shows latest time but shows check connectivity

 

Beacon status:Never reported
Beacon Web server status:Never reported
Last reported:2/1/2023 6:49:58 pm
Policy status:No policy

 

I have reinstalled/ deleted/ added beacon again. Nothing helped. 

 

We have upgraded FNMS from 2020 R1 to 2022 R2. No errors reported during the updade.

 

Can you please help.

Anything relevant in the BeaconEngine.log?

Your error message seems to imply that a connection to the FNMS server failed. Is your FNMS server itself operating normally?

The error details being seen here may be consistent with a situation where you had the beacon component installed on an application server, and then the beacon component was uninstalled. Doing that is known to break the application server configuration.

I'm not sure exactly what would be required to remediate the configuration. Some ideas to try are:

1. Re-run the Config.ps1 script to configure the application server.
2. If that doesn't help, do an MSI repair of the application server package and then re-run Config.ps1 again.
3. If that still doesn't help, maybe try installing the beacon software again and repeating the previous steps.
