After switching providers, the app may no longer be able to establish a connection while the recorder is still recording locally. First, investigate that difference. A router switch is not a reason to immediately remove cameras or reset the recorder to factory settings.
Use a connected screen or an existing local viewing location. Watch a recent clip and note which channels are available. This will clearly indicate whether the complaint is with the camera connection itself or primarily with accessing the system from a phone.
Compare where the recorder, switches and any network bridges are connected before and after the switch. A cable may have ended up on another port or in a different network configuration. Note which equipment has been replaced by the provider and which own equipment has remained.
An address previously set does not need to match the new router. Let the IP address, gateway, and required network services be evaluated. Bring the old data as a reference, but do not blindly revert them. The correct choice depends on the new configuration.
Open the app first via the home or business network and then via the normal connection outside the home. Note where the difference is. Existing account pairings and the supported access method must be checked before router settings are randomly expanded.
Search for a recent recording back via the app and check whether other users are keeping their agreed access. Save the new network data in the management overview. A working test on one phone is not automatically proof that all viewing spots are connected again.
This does not follow from the app notification. Check locally whether the recorder is still recording and if recent images can be played back.
Not only based on that change. First, the new network connection must be investigated.
