Hi, I have updated my RT-AC68U to 384.3. I could login after the update and then went to setup Let's Encrypt. The HTTPS Certificate was issued correctly (I downloaded the cert to see it). I then enabled HTTPS for the admin page on port 8443. I can now see my router Admin login page over HTTPS but my admin password is no longer working (error is "* Invalid username or password"). I use LastPass so it's not "user error". I tried all the passwords listed here but I still can't login. Luckily I still have SSH access as I have set up SSHD keys. Any ways to reset the admin password from the SSH console? Or is it the HTTPS on the admin page on port 8443 which is the problem here?
