I am trying to reconnect Time Machine to a backup server. It was used for Time Machine in the past.
After entering my credentials, I get the following error:
Your password on the server “server” needs to be changed.
You must change your password in order to access the server.
I am not sure what to make of it. I have reset the user password several times, tried shorter passwords, fewer special characters, etc. I keep getting this error.
I get the same error when trying to connect to the server from Finder. Some questions suggest the error might be permission-related, but this user has read-write access and I have not changed its permissions.
I looked at similar questions (about "MacOS Server") and I have deleted all Time Machine entries from Keychain already.
When I enter invalid credentials, the login dialog shakes, so I know the credentials are valid.
