I have a TS-233 NAS connected directly to my router running QTS version 5.2.10.3577. It has been working fine for several years as a backup for the data two computers. I usually shut the NAS down via the QFinder app when I set the PCs to hibernate for the day. Suddenly, starting last evening, I am receiving two warning messages in quick succession at about that time:
NAS Name: NAS60AA2B
Severity: Error
Date/Time: 2026/08/12 19:36:40
App Name: Users
Category: Login and Security
Message: [Users] Failed to log in via user account “admin”. Source IP address: 192.168.1.122.
Followed by:
NAS Name: NAS60AA2B
Severity: Error
Date/Time: 2026/08/12 19:36:47
App Name: Users
Category: Login and Security
Message: [Users] Failed to log in via user account “admin”. Source IP address: 192.168.1.122.
The Source IP address is my PC which is running Windows 11 Home.
Can anyone suggest why this should be happening, please?
