Unable to connect to Cloudflare R2 owing to lack of ability to change region

[seanvelasco]

Describe the bug
I'm trying to connect to an R2 bucket with Cyberduck using the Cloudflare R2 profile. However, I'm greeted with the following error:

The region name 'ap-southeast-1' is not valid. Must be one of: wnam, enam, weur, eeur, apac, auto. Please contact your web hosting service provider for assistance.

When I open the Cyberduck's settings (Settings > S3 > Default Bucket Location), I can change the region, and I can confirm the change is reflected, however the options enam, weur, eeur, apac, auto are not available.

To Reproduce
Steps to reproduce the behavior:

1. Install Cloudflare R2 profile
2. Use Cloudflare R2 bucket credentials and add bucket name as path
3. Attempt to establish connection
4. The above error is shown

Expected behavior
A clear and concise description of what you expected to happen.

Desktop (please complete the following information):

• OS: MacOS 15.0 (24A335)
• Version 9.0.2 (42108)

Additional context
When connecting using boto3, the same error is shown when using "auto", "ap-southeast", or any other regions other than enam, weur, eeur, apac, auto. In my case, when I used apac instead of ap-southeast, the error disappeared. So I believe the ability to change the region in the client will fix the issue.

I cannot reproduce. What region is the bucket in you are testing with?

hi, the region i set when i created the bucket was Asia-Pacific (APAC) or apac. in the Cyberduck client, the region in the S3 settings is set to Asia Pacific (Singapore) or ap-southeast-1.

i think the error is thrown when the region is not one of these enam, weur, eeur, apac, auto.

alternatively, can i change the region in my Cyberduck? when inspecting the .cyberduckprofile XML file, i found these options

<key>Regions</key>
        <array>
            <string>wnam</string>
            <string>enam</string>
            <string>weur</string>
            <string>eeur</string>
            <string>apac</string>
        </array>

but i couldn't find these options in the Cyberduck client at all. i just found these:
