However after the upgrade, the application was unable to add SBC devices via the SDM Device Manager, with the following error logged when trying add an SBC device:
Error occurs in processing data. Failed to validate Device Group '<DEVICE_GROUP_NAME>' for Network Function '<DEVICE_GROUP_NAME>'. The Telnet protocol service encountered an unknown error. Reason: Connection refused.
