Failed to log in

Warning] [QuLog Center] Notification from your device: TS-251B

NAS Name: TS-251BSeverity: WarningDate/Time: 2026/08/23 14:24:17App Name: QuLog CenterCategory: Connection StatusMessage: [QuLog Center] Failed to log in. User: xx Source IP: 192.x.x.x. Connection type: HTTP. Check the permissions and the connection.

Hello,

I get the above warning when ever I log in. The log is successful yet the message suggests otherwise. I have created a admin ID and disabled the original admin ID. I am very much the novice user with the NAS as local storage. I have checked permissions and connection. Nothing stands out as an issue. With the login successful it’s become an annoying message and welcome any insight as to why and what explicitly to check.

On another topic I am looking to upgrade the TS-215B to TS-264. Is there a link to how I migrate ? I have x2 4Tb existing and hope i just shut down the TS-215, remove the drives. Insert into TS-264. Power up and away we go ? I did say i was a novice. I am running the latest QTS..

Hope you can help

Hello,

there is a link
NAS System Migration Compatibility | QNAP

And can you post a picture with your settings.
Configuring system administration settings | QTS 5.2.x

No need to censor internal IP’s, millions have the same

192.168.0.x or 192.168.1.x are the most common either a client in your network or the NAS itself.

Investigate and report back.

Go to “Account Information Manager” in Windows and delete all entries related to the NAS. (I hope that’s what the menu item is called; it’s under Control Panel.)

Hello, Thanks for getting back to me. Here’s a screen shot

I have only the HTTP compression enable

And by security i have this


Could you provide the complete log information, including the IP addresses and timestamps? As discussed above, private IPs like 192.x.x.x don’t need to be masked. That said, if you still have any concerns, you’re welcome to send the log screenshot to me via private message instead. Thanks!

Above is the email I receive

below is the NAS logs

Hello,

You may try to go to QFinder Pro and select your NAS and click on Configuration to enter the login credential again and check Remmeber me checkbox.
