3-access-secret qwerty123 --password qwerty123 --username anon --sftpd-port 9090 --fs-provider s3fs

What are you using SFTPGo for?

Private user, home usecase (home backup/VPS)

Additional info

--directory works just fine

Try setting the s3-region option for sftpgo.

This option is mandatory on the sftpgo command line, but not treated as such in the CLI.

Its possible to not set it, and it will generate an error at runtime when sftpgo initializing the s3 client.

For minio the default region is us-east-1

    --s3-region us-east-1 \

Here is the complete command

sftpgo portable \
    --s3-bucket geesefs \
    --s3-endpoint http://10.0.0.64:8012/ \
    --s3-region us-east-1 \
    --s3-access-key qwerty123 \
    --s3-access-secret qwerty123 \
    --password qwerty123 \
    --username anon \
    --sftpd-port 9090 \
    --fs-provider s3fs

Try setting the s3-region option for sftpgo.

Still the same. But behavior has changed somewhat. Previously, the error was given instantly, but now it takes a few seconds.

Is there a way to get some kind of debugging log into the console?
