Hello,
so i upgraded a couple hundred of my Routerboards yesterday
(v6.45.1) after upgrading the packages, I also upgraded the firmware and performed a final reboot on every Routerboard.
Everything went fine, and everything was working,
however, one device (RB3011) reports “ERROR: wrong username or password” when i try to access it via WinBox (3.18)
The funny part is:
I can access this Routerboard with exactly the same username and password via WWW or SSH.
I even get the failed login attempts in the ssh cli:
07:42:48 echo: system,error,critical login failure for user admin from 10.48.99.13 via winbox
(Yes, i checked for typos and yes i am using a password manager to copy my credentials)
I tried to reboot the router, i also tried a hard reboot with cutting the power,
i checked the installation → OK,
but nothing seems to work.
Winbox service is enabled:

Firewall is set up correctly:

any clue?
thanks guys!
edit: i just tried to connect via Mikrotik Android App and i get the following log entries:
user admin logged in from 10.48.99.22 via winbox
However, the app is stuck at “connecting…” screen.
