There are two main issues that can arise regarding a connector:
- An application is unreachable.
- Connector availability issues.
- Connector misconfiguration.
In most cases, an application cannot be accessed by a connector for one of two reasons:
No network access from the connector machine to the application
Check if the application can be reached:
HTTP: curl -kfsSLv -m 5 http://internalIP_or_FQDN:port HTTPS: curl -kfsSLv -m 5 https://internalIP_or_FQDN:port SSH: curl -v telnet://<internalIP_or_FQDN>:22 RDP: curl -v <internalIP_or_FQDN>:3389
In case an application cannot be reached, ensure there are no routing or firewalls blocking access from the Connector to the internal apps.
Connector machine is configured to a different DNS server than expected
In some cases the connectors are on a network where a different DNS server is utilized than expected. Running the following commands checks whether the Connector is able to resolve internal applications via DNS:
- nslookup hostnameORfqdn
- dig hostnameORfqdn
You can tell whether the connector is not available by checking the connectors page in the Management Console. Go to Settings -> Connectors.
Connector is unavailable to serve all applications
In case a connector is unavailable to serve applications, try the following steps:
- Try to reboot your machine.
- To make sure a firewall isn't blocking outbound connectivity from Connector to the Axis backend. When it works it will end with displaying some certificate information:
The following command checks connectivity to Axis Security:
curl -kfsSLv -m 5 backend-tcp.axissecurity.com:443
Connector is available to serve only agentless applications
If the connector shows that it is available for agentless only (which means, not available to serve agent-based applications), verify the following:
|1||The UDP ports are open outbound on the firewall.|
|2||The proper resources are assigned to the connector (4vcpu/8gb Ram).|
|3||The changes in the Axis management console have been applied before pasting in the Curl script|
If your connector is not working, use the following table to check for the following:
|1||Your outbound firewall rules aren’t open|
|2||Your changes have been applied and committed in the Axis Management Console|
|3||You have assigned the correct network interface to the connector|
