This article provides troubleshooting steps to resolve the issue where an SRX cluster device is unable to establish a connection to the SD Cloud

During the issue, the SRX device fails to establish a connection to the SD cloud on port 7804, even though a telnet test to the SD cloud on port 7804 is successful.

The SD Cloud provides outbound SSH group configuration for both nodes. However, if the apply-group is deactivated, this configuration will not take effect.

To verify whether the apply-group is active, run the following command:

show configuration | display set | match apply-group

If the apply-group is deactivated, you will see a line similar to:

deactivate apply-group "${node}"

Make sure the apply-group is not deactivated for the SSH configuration to be effective.
