i just installed on both my unraid servers and when i try to connect from one filezilla server to the other i get premission denied. i use no user or password. both are on local network. what am i doing wrong?

I have the same problem, i had no power for several hours and now when i start unraid i cant access ple gui. And i have the same error. How do i fix it?
