[Bug] Garage S3 doesn't work behind a reverse proxy

[Arlind-dev]

Describe the bug

When using garage with

this config

storage-type: "themeinerlp:s3"
compression: gzip
bucket-name: "bluemap"
region: "garage"
access-key-id: "REDACTED"
secret-access-key: "REDACTED"
endpoint-url: "http://garage:3900"
root-path: "srv1"
force-path-style: true

it works, but using it like this:

storage-type: "themeinerlp:s3"
compression: gzip
bucket-name: "bluemap"
region: "garage"
access-key-id: "REDACTED"
secret-access-key: "REDACTED"
endpoint-url: "https://s3.local.domain.tld"
root-path: "srv1"
force-path-style: true

It does not, the error will look like this:
