Can you provide me a "mc.exe config host list" output please, to do further root cause analysis?

[vadmeste]

It would be also great if you run the command again with --debug flag and paste it here. @runner-mei

[mei-rune]

Now I'm resting, no environment. But I know why, “mc.exe cp -r lib\minio local” will “minio” as the bucket name, send request to "http://127.0.0.1:9000/minio", but "http://127.0.0.1:9000/minio" is gui url.

You can reproduce it yourself:
md lib
md lib\minio
echo aaaa > lib\minio\aaaa.txt
mc.exe cp -r lib\minio local

Yep this can be reproduced @runner-mei

FWIW a regression was introduced on the server which leads to this error.

    web: Validate if bucket names are reserved (#3841)
    
    Both '.minio.sys' and 'minio' should be never allowed
    to be created from web-ui and then fail to list it
    by filtering them out.
    
    Fixes #3840

[harshavardhana]

We need to open a server bug here @CarterMcClellan @vadmeste
