Can't guess your region for bucket problem

[jueshali]

When I tried to connect to s3, the following error occurred, and I didn't find that I could set the region parameters. Am I missing something? Following is my status code. Thanks a lot for help.
Object storage: Can't guess your region for bucket : AccessDenied: Access Denied
status code: 403, request id: CJ0Q3ZFSEX1W6K5Y, host id: j1w7L/6CUUxQ11OI6

Can you provide the complete juicefs format command? Looks like the --bucket option is incorrect.

My S3 storage address is tokyo, and I changed the system variable setting echo $AWS_DEFAULT_REGION = ap-northeast-1，but it doesn't work @xiaogaozi

Currently, JuiceFS only support virtual hosted-style URI. So you need specify --bucket looks like this:

$ ./juicefs format --storage s3 --bucket https://<bucket>.s3.<region>.amazonaws.com --access-key **************** --secret-key **************** localhost gdc-tokyo-test

Replace <bucket> with your bucket name and for Tokyo the region is ap-northeast-1.

Yes, thanks a lot. I found the relevant code, I hope this can help other people who use this software and encounter similar problems

if strings.Contains(uri.Host, ".amazonaws.com") {
			// standard s3
			// [BUCKET].s3-[REGION].[REST_OF_ENDPOINT]
			// [BUCKET].s3.[REGION].amazonaws.com[.cn]
			hostParts = strings.SplitN(uri.Host, ".s3", 2)
