What provider and architecture? Original post had duplicati/duplicati ArmV7.
I don’t know what test setups the Duplicati devs have, but specifics will help.
If anybody’s on LSIO, results might still be informative on what spot got bad.
Ditto for anybody not Docker at all, in which case system info may be useful.
So aside from a Backblaze issue that may be separate, this is all OneDrive?
I’d note that there’s another maybe wider SSL certificate topic in forum lately.
Having one that can be well-isolated if possible might help narrow bug down.
Personally I don’t do Docker, and OneDrive is doing well for me on Windows.
