unable to connect all agents to ESMC server

[Orionz 0]

Hello,

I'm new to ESMC. I've installed ESMC 7.1 server, made deployment package and installed it at 8 PC's.
All of them are downloading AV updates from server with no problem. However only 3 of them are visible at ESMC web server console. There is no track of missing 5. Could you guys tell me, where to start diagnosing this problem?

Please check C:\ProgramData\ESET\RemoteAdministrator\Agent\EraAgentApplicationData\Logs\status.html  and trace.log on not connecting clients for possible errors.

Looks like the agent is unable to connect via hostname and able to connect via IP. Is there a way to deploy installer with IP instead of hostname?

In ESMCAgentInstaller.bat you can edit the server on the line commencing with "echo.P_HOSTNAME="

Making new agent installer with IP address worked. Thank you for your help.
