calibre-server log in Ubuntu showing unexpected "failed login attempt" messages

I'm not sure why I'm getting logged messages in the "calibre-server.log" file that show "Failed login attempt from: <my home IP>" when I've never had a failed login.

I have the server running on an AWS t2.micro Ubuntu server with the security group only allowing inbound access from my home IP, so I know others are not getting there.

I started the server in systemctl using the following:
Code:
ExecStart=/usr/bin/calibre-server /home/ubuntu/calibre-library \
          --port 2345 \
          --userdb /home/ubuntu/users.sqlite --enable-auth \
          --ban-after 5 --ban-for 360 \
          --log /var/log/calibre-server.log --max-log-size 100
And see the following in the output file
Code:
$ cat /var/log/calibre-server.log 
calibre server listening on 0.0.0.0:2345
OPDS feeds advertised via BonJour at: 172.31.93.216 port: 2345
Failed login attempt from: MY.HOME.IP.ADDR
Failed login attempt from: MY.HOME.IP.ADDR
after logging in successfully. Even if calibre-server doesn't record successful logins, I shouldn't be seeing any errors, since there was one and only one login attempt which let me in fine.

Any thoughts why this is happening?

Use --access-log to see who is accessing the library. And if you see a failed login attempt, that means something tried to connect to the server with HTTP auth headers containing incorrect values/no auth headers.

Thanks. I'll go add that startup flag. And thanks for the hard work and dedication you put into such a cool product!!!
