Original GitHub issue: https://github.com/s3fs-fuse/s3fs-fuse/issues/2458

I tried to mount a s3 bucket created in eu-south-1 region in my linux ubuntu server 22.

This is my command:
s3fs bkt-storage:/storage /mnt/s3storage/ -o passwd_file=/etc/aws/.passwd-s3fs -d

My /etc/aws/.passwd-s3fs is formed like this:
PUBLICKEY:SECRETKEY

When i run this command with root user, I don't get any response, but looking into /var/log/syslog I find this errors:

I tried to add -o url=https://s3.eu-south-1.amazonaws.com option, with no luck.

Do you know how to solve?

I solved adding two options: endpoint=eu-south-1 and url=https://s3.eu-south-1.amazonaws.com.

Finally my fstab line is this:
myname /mnt/s3-myname fuse.s3fs _netdev,allow_other,passwd_file=/etc/aws/passwd-s3fs,endpoint=eu-south-1,url=https://s3.eu-south-1.amazonaws.com 0 0
