MikroTik

Hi Just upgraded 2 routers with 6.35.2 via winbox>packages>check and install. After upgrade, Im unable to login by SSH or winbox. Winbox does not connect and SSH disconnects presumably for incorrect password. MAC telnet has same response. Anyone have some insight on this. I have no doubt I know my credentials. I am well versed in MT as well.. HELP?

router 2011 ah
 and 951

I had the same issue but I do log in after several tries
