What I've tried to do already
- Disabling and enabling "Proxy thumbnail generation" and "Proxy media extraction" in policy settings
- Disabling file encryption in policy settings
- Disabling and enabling all the generators and extractors in Settings > Media processing
For whatever reason enabling upload relay allows uploading all files without an error. Though I'd like to use direct upload to S3 as this provide significant speed improvement over upload relay.
