Admin Panel Bug

Router: GL-MT6000 Flint 2
Version: 4.6.3-op24

I was using version 4.6.0-op24, but recently encountered a login issue as described in the link below.
https://forum.gl-inet.com/t/gl-mt6000-admin-panel-password-not-working/
So I upgraded to 4.6.3-op24 and also did a reset, but now the admin panel is not working.

Bug Symptoms:
After changing the router address from 192.168.8.1 to 192.168.1.1 and rebooting, the GL-iNet admin panel page does not work.
Accessing 192.168.1.1 takes me directly to the LuCI page instead of the GL panel.

I thought it might be a browser cache issue, so I tried accessing it in incognito mode, but the problem persists.

How can I resolve this issue? Thank you for reading.
Please understand that I used a translator because I am not good at English.

No bug, clear cache...
