So i'm coming back to the server after a few years off and 3 of my characters doesn't have a name and can't log with them, only my main is normal, any clue how to fix this?

they have been flagged for a rename due to inactivity.

Log them as usual. When asked to type a new name try to use the old name (maybe those old names are still free).
If those old names are taken -> select a new name
