Hi Asgardius, thanks for this app, it would make my workflow much easier as we have backups on Backblaze.

I am trying to configure it following this guide.

The only difference is that my S3 Endpoint is preceded by https://. The region I insert is like the suggested us-west-001.

When I test the credentials I get (I am using adb logcat):

03-07 10:55:48.738 13009 13059 W System.err: java.lang.IllegalArgumentException: Region cannot be null. Region is required to sign the request

Moreover, every time I now select my newly created account the app crashes with a similar issue

Is there anything I am doing wrong?

Thank you in advance!
