Sorry about that. The log I had before might've given you the wrong idea. Actually, the error we run into a lot is "Could not find system commissioner pairing for newly staged server with identifier 6f:d6:63:43:b5:b9 in all pairings:", not "Failed to open pairing window on the device". I have uploaded the log with the ID: FB17357284 Could you assist us in resolving this issue? Thank you.

Sometimes, it doesn't even send the "open pairing window" command. It just gives an error right away. Do you know why that is? 错误 13:59:42.963124+0800 homed Mdns: Resolve failure (src/platform/Darwin/DnssdImpl.cpp:697: CHIP Error 0x00000074: The operation has been cancelled) 错误 13:59:42.963193+0800 homed OperationalSessionSetup[1:0000000023C84E43]: operational discovery failed: src/lib/address_resolve/AddressResolve_DefaultImpl.cpp:124: CHIP Error 0x00000032: Timeout 错误 13:59:42.963254+0800 homed Creating NSError from src/lib/address_resolve/AddressResolve_DefaultImpl.cpp:124: CHIP Error 0x00000032: Timeout (context: (null))

Hello. I would appreciate it if you could kindly help to solve this problem. Thank you very much! I have already filled in the relevant information in the feedback assistant and uploaded the sysdiagnose file： -- FB17317942 please file a bug describing what happened --When using our app to scan the QR code for adding a Thermostat (Matter Over Thread), an error occurred, stating: "Unable to Add Accessory". what time the failure occurred --2025-4-22 16-17 GMT+8 What system versions have you tested with/seen this on? --iOS 18.4.1 Can you provide more details about what you're controller configuration you're testing with? What's the pairing device (the device you're using the pair UI on), is there a Home Hub, and device(s) are acting as the bridge to Thread? --We don't have a Home Hub. Instead, we're using our own Matter Controller, which is also a Thread Border Router, and our Thermostat that works with Matter Over Thread. What's the ratio of success/failure when pairing? --When the network's good, the success rate's really high. Nine out of ten attempts are successful, and there's just one failure. --When the network's bad, the success rate's really low. Nine out of ten attempts are failures, and there's only one success.

I am a colleague of the original poster MarcoKhoo. I would like to supplement with the complete log of the issues we have encountered.
