[error] Cannot establish communication : 500 Internal Server Error

1) using debian package 2:2.8-2 amd64
/usr/bin/ocsinventory-agent --debug --ssl=0 --nosoftware --force -s http://10.10.0.254:8081/ocsinventory 2) using github devlibs clone cd repo && ./ocsinventory-agent --devlib --debug --ssl=0 --nosoftware --force -s http://10.10.0.254:8081/ocsinventory

same result using agent on server and remote lan 2 clients

client_1.log client_2.log client_3_onserver.log

ANDROID CLIENT OK!!!

WINDOW CLIENT OK!!

INJECTOR same as client

./ocsinventory-injector.pl -f /root/UnixAgent/dl360g7-2022-11-05-18-55-32.ocs -u http://10.10.0.254:8081/ocsinventory -v --sslmode=0

Hi,

In order to have more information, could you enable the DBI_PRINT_ERROR in the z-ocsinventory-server.conf file ? Then try to use the injector again, you'll have the SQL Query leading to empty dataset.
