Thank you very much,
Thanks to your sk links I think I found the issue explanation. Appi_status.C file show an empty value on variable
app_db_version () and I have this app_update_description :
"Update failed. Gateway can not access internet ('https://secureupdates.checkpoint.com/appi/v4_0_1/gw/Version'). Check connectivity and proxy settings
I didn't understand internet access was also needed on Security Gateway, A proxy was only configured on the management server.
Is there any other way to get application dabatase update without configuring internet access on the gateway ? For example retrieving update from management instead ?
