Would a create-report submission from a usage reporting related crash be useful? I think there are a few users who would be willing to submit one.
Also, I just got a log from this post that shows 53 entries, 51 of which are Error: UsageReporter failed.
Since my tests with usage-reporter.duplicati.com blocked in my hosts file don’t produce any errors I’m wondering if it could be that the usage-reporter server is overloaded? (Not accessible is different from (500) Internal Server Error.)
