Cloudflare R2 bucket

I hope you guys are well.

I don’t seem to be able to add a new S3 connection to my Cloudflare R2 bucket on Android.
No matter what I try, I always get a “No such bucket” message. To test I also tried to enter a wrong URL/wrong username/wrong password/wrong bucket name and always the same “No such bucket” message.

Note: I was able to connect to it on mac using the following profile on Cyberduck:
which I found in:

Thanks for your help!

Similar issue with OCI object storage

Works with cyberduck using the profile listed in:

But on the Android App I get “An error occurred” no matter what I try.\

Thanks for looking into it.

Hey and welcome to the Cryptomator Community :slightly_smiling_face:,

Currently Cryptomator for Android requries for S3 the Allow List All Bucket Names scope, do you have enabled it for the entered access credentials?

If so can you please enable debug mode, reproduce the problem and send us the log file?


Thanks for replying.

I’m not sure where to set Allow List All Bucket Names as I’m trying to use Cloudflare and Oracle in S3 compatibility mode, I couldn’t find/don’'t think I have this setting.

Just sent the logs by email (created Ticket#82060).



When there is only a single S3 connection (bucket) configured, the app works fine regardless the provider I use (tested with BackBlaze B2, Cloudflare R2 and Oracle object storage)

The problem seems to happen when I try to add a second bucket from a different provider. It seems to be reusing the url/credentials from the first configured bucket.

I sent a few more log files.
