Can't get connectedDevicePointer. Probably because of DNS-SD flakiness

I downloaded a simple app for matter on the Google development platform, but used it to add a curtain matter device that has been added to the local development structure. When I connect, an error is reported as follows:

Unable to get connected device with nodeId 1. mDNS flakiness???

Unable to connect to the device. What's the problem?

It is very hard to investigate the issue without more information.
