Per our conversation, you have a Cosy device that continues to drop the connection every 10-30 minutes. You updated to the latest firmware last week, it hopes to resolve this issue. However, the it still persists.
As discussed on the phone, you have a technician on site that will be downloading the back up file with support files. Once you are able to get that information, please attach the backup, and we will be able to continue our troubleshooting process.
Please let me know if I can provide any additional information.
