That’s great to hear. Is there a canary build I should try?

Not yet. I am pulling a few things together and hope to have a new canary out this week.
One thing that came to mind was that the “cleaning” seems to remove only a single slash, so you should be able to get it working with:
```plaintext
[bucket]///t/
```
And yes. It is getting a bit ridiculous and will only work until the fix I made makes it into the release.

Of course, I can’t believe I didn’t think of that since I looked at your commit. I just put 2 slashes on the destination in the configuration, and it works fine.

[2.1.0.110\_canary\_2025-02-28](https://github.com/duplicati/duplicati/releases/tag/v2.1.0.110_canary_2025-02-28) is presumably the new canary that was forecast.

Yes.
But due to another bug, you can also now update to [2.1.0.5](https://forum.duplicati.com/t/release-2-1-0-5-stable-2025-03-04/20279), which also has the fix for the missing `/`.

Happy to report that everyting works. Without or without the / on the front.
Thank you and thank you @ts678
