Error starting NGP Host Service

If port 20111 is busy during installation of Axxon Next (for example, because of nethost.exe processes that have not been unloaded since removal of the previous version), an error message regarding the launch of NGP Host Service appears.

To continue installation, free up port 20111 and try again.

Error connecting to the Postgres Database

After installation of the Postgres database, the Axxon Next installer may quit prematurely. This situation may be associated with the inability of the installer to connect to the Postgres database, if the firewall is enabled. To prevent this, disable your firewall during installation.

Note

Disabling the firewall during installation can cause another problem—see No signal from video cameras and failure to connect to other servers.
