ArcGIS Server does not start the service properly. Checking the /framework/etc/service/logs log file in the installation directory keeps indicating the following error:

“ERROR: Unable to start the RMI connector for NodeAgent”

The initial judgment is related to the network.

The first step is to check the system network information.

Linux environment: use ip addr or nmcli , where you have to make sure IPv6 is turned off.

Step 2, if IPv6 is not turned off, you can turn it off by modifying sysctl.

Modify the /etc/sysctl.conf file and add the following two lines.

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

Execute sysctl -p to take effect.

Step 3 Start the ArcGIS Server service again.
