Hi @rickard - thanks for using (and liking!) Duplicati!
It sounds to me like you’ve got a slow connection and it’s Duplicati gives up waiting for OD4B to respond (hence the “timed out” error).
You didn’t mention what version of Duplicati you’re using, but if it’s one of the newer Canary versions you should have access to the --http-operation-timeout parameter which lets you extend how long Duplicati will wait for a response from your cloud provider.
Note that I believe the default timeout is 10 minutes, so if you’re finding that the error comes up 10 minutes after the last step then that’s a good confirmation we’re on the right track.
(BTW - I edited your post by putting “~~~” before and after the error message to make it easier to read.)
