I am using Ubuntu Server to run my MineOS server. Everything was going well until I changed my password on my Linux terminal, I used the command passwd. I tried to use the new password on the web page, but it doesn’t work. Any help would be greatly appreciated. 
hi,
i’ve setup my mineos just today on ubuntu and ran into the same problem. Probably has something to do with pw encryption
login as root,
usermod -p password username
should take care of this
