Unable to access router by SSH or WinSCP after changing to AP mode

[newnews]

Hello,

I now use Raspberry PI 4B as my main router (openwrt installed), it is amazing so far. I then change my original router RT-AC68U to AP mode connecting wired to Raspberry Pi. Everything works as expected so far. The only strange thing is I can access the router from web GUI, however, it keeps saying wrong password if I access from SSH or WinSCP using the same password.

What is the problem?
What I need is to see which processes are running in the RT-AC68U. If accessing it by SSH in AP mode does not work, is there any way to see the processes from web gui?

thanks

Might be a stupid question.. but after switching modes on your Asus router, did you check the "Admin" tab to see that SSH access with a password was still enabled?

it is enabled.
Anyway, I disable SSH and then enable again, SSH is working!
