I'm trying to initiate an S3 object storage sync with os.alp2.flow.swiss

Flow Swiss does not use regions or endpoints.

With Cyberduck, I am able to type in any old AWS region and it will work. I have done that here (Region: us-east-1).

The "Check Synchronisation Configuration" indicates success when I do this in Joplin Linux.

The following error message is with "force path style" checked, and encryption enabled -- but I get the same or very similar error message with force path unchecked and no encryption.

Any ideas? THANK YOU!

Error

The sync target could not be upgraded due to an error. For support, please copy the complete content of this page and paste it in the forum: https://discourse.joplinapp.org/

The full error was:

Could not upgrade from version 1 to version 2: write after end
