The "Remote Connection Limit!" message indicates that the NVR has reached its maximum allowed external connections from WAN or LAN. This limit is inherent to each NVR, and when exceeded, the app or client software displays this message.

Navigate to the NVR Main Menu.

Select "Maintenance." Then find the "Remote Channel" option.

Disconnect unnecessary channels or disconnect all channels.

Recheck your app or client software.

By doing this, you manage the remote connections on the NVR, resolving the issue. If the problem persists, reach out to technical support for further assistance.
