I’ll mention some things. Jottacloud changed authentication, but Duplicati’s partial fix is pending, however this other thread is suffering from a different error. Jottacloud support for us is limited.

There’s also a Duplicati workaround there using rclone which also seems to be glitching with Jottacloud.

[Implement exponential backoff for backend errors #4661](https://github.com/duplicati/duplicati/pull/4661) is another option so far just in [Canary](https://github.com/duplicati/duplicati/releases/tag/v2.0.6.102-2.0.6.102_canary_2022-04-06) releases which you may or may not want to use for serious work, as Canary can add bugs along with good things.
